Testimonials

We decided to start this testimonial page in October of 2013. If one was to ask us why we waited so long, we would have no sensible answer.

If you would like to be so kind as to offer a submission for the page, please email us with your comments. All testimonials will go up with the sender’s first name and location.

We offer our sincere thanks to all of our clients who take the time to let us know how much they love their stones. Your kind notes of appreciation are what keep us doing what we do.

As a collector I have seen many rock sites, but none match the quality of Jack and kathi’s stuff.

I first started purchasing on ebay when Jack was just starting out and noticed the quality instantly. Ever since that I have been buying from only them. Everything they get is of the best quality. Most is all hand picked by them, and they put alot of time into what they do.

They get stuff I have not seen anyone else carry, and when I purchase I let them pick my stuff, as I know that I’ll be getting the best of the best.

They also have some of the best shipping I have ever seen. All stones are bubble wrapped to the extreme. You wont have to worry about anything ever being broken unless it falls out of the plane.

All photos are well taken for their ebay listings and website, whereas a lot of others only have 2 pictures or show you only one side of the stone, and all of there stones have a perfect polish.

I have never had an order that I didn’t like from them. 10 out of 10 easy!

What an emotional, exhilarating, and enthralling experience visiting you and your show room. I couldn’t have felt more welcomed and honored to experience your collection. The love and pride that you take in the personal selection of every stone shines as brightly as each crystal. I have recently began a journey that includes the energy work of crystals. The quality and selection of pieces were exactly what I needed to jump start my own collection. I have been hesitant to buy any crystals on line, but, after meeting you and seeing the exquisiteness of your inventory, I look forward to buying many more pieces from you! Thank you so much for everything. I highly recommend this shop for all crystal lovers! With gratitude, Marian Chattanooga, TN

Marian | TN

Awesome selection, Jack was extremely knowledgeable and made a very personable experience. Kathi’s krystals is now my go to shop.

Muff Stuff | CO

What an amazing selection! Everything is exceptionally high quality, and the stones are beautiful. We planned on going in for about 30 minutes and stayed for almost 2 hours. Great place!

Jonny | CO

Going to Kathis Krystals for the first time today was a wonderful experience! Jack is incredibly knowledgeable and kind. The stone selection is a huge variety of beautiful and rare stones, and the prices are fair. I will be back no doubt!

Kristen | CO

Amazing variety and quality. This is the real deal! Jack was awesome and so knowledgeable- I can’t wait to go back.

Catherine | CO

Had a great time “rocking out” with Jack over the course of several hours and two visits. Totally unique experience, great people, awesome collection. Highly recommend.

D H | CO

What a gem of a place!! (Pun intended). Seriously though, it’s a fun experience to see such an array of beautiful stones. At Kathi’s Krystal’s, the owners certainly have no shortage or sparkly items, but they go above and beyond to tell the origin of each crystal. My son Oliver is obsessed with crystals, and he can’t stop talking about Jack and his rocks. Call first to make sure they are open, as the shop is operated out of the home.

Christina | CO

I’ve never seen a collection like this at any show or shop. Jack’s knowledge of and excitement about the rocks makes this more than just a shopping experience. Strongly recommend a visit!

Tony | CO

Jack and Kathi are both super friendly folks with a very extensive selection of high quality stones and crystals! Very reasonable pricing as well. Will definitely be back and highly recommend checking them out!

Sydney | CO

When I spoke to Jack on the phone to make an appointment and told him I just wanted one stone and planned to leave my dog in the car, he warned me that it would not likely be a ten minute experience and should plan for more time! 30 minutes later and an absolute time boundary pulled me away but I could have been there for hours. Think museum plus crystal shop with every stone you could possibly imagine. A few I never thought I would encounter without ordering online. Jack and Kathi were super hospitable and knowledgeable. This will definitely be a new favorite spot!!

Genesa | CO

Every year my fellow teachers and I gift a stone to each of our graduating elementary students. We choose somethings that represents their qualities and gifts. The stones are presented at the graduation ceremony.

We began this tradition in 2014 and after searching many web based venues for ordering stones we discovered Jack and Kathi’s site. We order exclusively and confidently from them because the quality of the stones is excellent. We know exactly what we are getting because the site is set up to sell you the exact stone you select.

Each stone has dimensions listed, info on the how and where it was acquired and multiple photos to show it from every side-no hidden surprises. Stones are photographed from two perspectives; held in the palm of a hand and with light shining through it.

Jack is immediately responsive to questions and comments, ships items quickly and well packaged and includes a velvet drawstring pouch and a laminated information card along with each stone. They offer a wide range of options and prices for each type of stone.

Most importantly for me, Jack and Kathi manage to create a personal shopping experience by their communication and responsiveness. It is because of how they manage their business, and the quality of the stones, that we created this tradition of continuing to gift stones to our graduates each year. And each year at this time, the graduates talk excitedly, that they cannot wait to receive their own personal stone from Jack and Kathi! Thank you for your commitment to your customers and the quality of your stones!

Karen | Ithaca, NY

I received my Arfvedsonite stone today. She is beautiful exactly as in the photos. Many thanks for your excellent service and fast delivery.

Karyne | Canada

Just wanted to let you know my box arrived in today’s mail. I’m 100%-plus satisfied with the delivery and packaging — and the sardonyx and peridot are absolutely beautiful. The little red and green bags make a great presentation and are perfect for Xmas. I know my hubby will be very pleased with this gift! Thanks for taking such great care of my order.

Liz | CO

I just wanted to let you know the parcel has already arrived(!) That was lightning fast to Canada! 🙂 The stones are amazing and absolutely OUTSTANDING! I am over the moon and am deeply enraptured by them at the moment. These Lepidolites are incredible(!), I am just blown away, I can’t even write at the moment, too distracted by them all, lol! 🙂 The rutile quartz you sent as a gift is STUNNING, thank you so much! you are both very gifted in finding and selecting gorgeous stones to offer and I am grateful! 🙂 Kindest regards

Nicole | Canada

I found you to be extremely invested in making sure you understood what I was seeking, interested and concerned about the crystals I wanted and that you got them to me very quickly. They were even more beautiful than pictured and I was completely happy with every one of them. I use them in crystal layouts when I do Reiki healing. I am especially happy that they were of such good quality and so beautiful because I have grown very attached to them as they are faithful allies in my healing efforts. Blessings.

Pam | Illinois

I was delighted to find Kathi’s Krystals on eBay several years ago, and I’ve been an avid follower ever since. If you are looking for exceptional fine minerals, Kathi’s Krystals should be at the top of your list! Kathi’s carries some of the finest material I have ever seen, and I’ve been collecting gems and minerals for over 40 years. Kathi’s specialize in hard to find and exceptional pieces, as well as a full sampling of the more popular stones, and takes great care in their selection to bring only the best to their customers. I have never ever been disappointed by a purchase, and have been thrilled to display several of my Kathi’s finds in various art works. Thank you, Kathi’s Krystals, for your consistent superior quality, inexhaustible focus on finding the best stones possible, and wonderfully friendly customer service! It is always a pleasure doing business with you!

Debby | Nevada

Definitely one of the best designed web sites I’ve ever seen! The photographs of the crystals are simply awesome. As a customer it really helps to be able to see the actual crystal, in different lighting and at different angles. This way you know exactly what you’re getting. Plus the “hand shots” really help in being able to judge their size. It’s a nice touch. (no pun intended)

Needless to say I could spend hours just looking around the web site!

As for the crystals themselves, the many that I have purchased have all been of the highest quality. Customer service is second to none, with Jack treating you more like an old friend than just another customer on the internet.

Thank You Kathi’s Krystals, I wish you success!

Ron | Colorado

When I first saw the website to Kathi’s Krystals I was amazed. The pictures were beautiful and because I am especially attracted to the metaphysical qualities of rocks, crystals and stones I was happy to read about these particular properties. I would browse through the pictures and was impressed by the quality of the stones but more impressed with the obvious care that was taken in photographing each piece. I was especially drawn to the palm stones. When I received my first stone it was magical. The lapidary work was amazing and the best part was it was better than the picture. I became an addict. I bought so many stones and gave just as many away. Each one felt like it was loved and cherished before it came to me. The cards that accompany the stones are an extra bonus. They always arrive fast and in great condition but mainly I would say these are simply magical.

Jasmine | California

Kathi’s Krystals is a treasure trove with a wonderful website, amazing customer service, and incredible stones. Their meticulous attention to detail matches their high integrity and both are reflected in the superior quality of their products. You will quickly feel like a valued member of their family. Once you get a taste of the wonderful experience that is Kathi’s Krystals you will never want to shop for stones anywhere else again.

Angela | Colorado

Kathi’s Crystals has many beautiful quality crystals to purchase. The website is easy to navigate and each stone is photographed from several angles. The dimensions are listed and pertinent facts about the stones are given. This comprehensive website has a listing of types of crystals for sale in the left hand column. Under each type are listed the individual crystals for sale. The quality of the stones are evident by Jack’s painstaking photography. The crystals are shipped securely, nestled in a velvet pouch, wrapped in bubble wrap and surrounded by paper inside a sturdy box.

I use the palm stones and worry stones for crystal healing and divination. I use the hearts, eggs and spheres mainly for display purposes. I heartily endorse Kathi’s Crystals for all of your crystal needs!

Marcie | Oklahoma

In my years of dealing with Kathi’s Krystals, and with the numerous purchases I’ve made, I’ve always been very pleased both with the quality of the beautiful and interesting stones and with the great service Jack & Kathi provide. I recommend Kathi’s Krystals most highly for anyone seeking the best possible experience in acquiring gems and minerals.

Lyman | Texas

As both a serious collector of mineral specimens and a practitioner of crystal healing, it is rare that I find one particular seller who meets both those needs. Jack and Kathi of Kathi’s Krystals happen to be among those rare vendors. First, their stones are of exceptionally high quality. I have never been unhappy with the selections I’ve purchased from them.

Second, they have gone out of their way to accommodate those times when I have found stones on both the Kathi’s Krystals website and their ebay store at the same time, making it possible to get them all in one shipment and thus save quite a bit of money on the shipping costs, even though I’m sure it meant extra work for them in combining orders from the two different venues.

Lastly, and most important to me, they have gone out of their way to make sure that I am happy with everything I receive. They communicate with their customers, they care about them, and they “go that extra mile” in making sure that what they receive exceeds expectations. In this age of impersonal customer service, I have to say it’s quite refreshing to find anyone who puts themselves second and their customer first.

As long as I’m collecting, you can be assured I’ll continue to be a very loyal customer!

Mark | Texas

Mostly what I can report is WOW, what a find we discovered when I located Jack and Kathi’s contact info and was able to meet up with Jack the other day; my treat for my 9-year-old and 6-year-old grandsons, to view and purchase some treasures.

This is NOT your everyday Rock Shop but a sampling of what it is like to be treated with kindness, respect and Jack’s wonderful ability to be patient while the boys were sorting through many, many specimens. Jack’s passion for collecting and sharing what he does is apparent immediately, (he did not try to sell us anything), and we were amazed at the amount of time we spent on the floor, just enthralled with Jack’s inventory, his desire to identify and discuss each specimen, then simply and kindly move on to the next treasures. Yes, we did make a few purchases, we were treated to a few freebies, and most of all, we have a new friend that we will visit again soon. We will enjoy knowing exactly where to go when we want to experience all Jack has to offer. I hope to meet Kathi someday soon as well, and enjoy viewing her handcrafted jewelry. Thanks Jack. The boys are still showing off their purchases and I expect we will surely be calling you in the near future.

Quotes from the boys while in the car, heading home: “We love Jack and Jack is great and we want to go back.”

P.S. A bonus part of this experience was meeting and playing with Jack and Kathi’s adopted pup Okie. They have one unique and special dog!!! I am a “rescue person myself” and I am thrilled that this pup was lucky enough to have found this terrific home.

Janice, Andrew and Christopher | Westminster, CO

Getting to visit Kathi’s Krystals was one of my most special and fondly remembered times during my visit last year to Colorado. Their collection of stones was fascinating and Jack spent over an hour talking to me and my friends about the collection and patiently going through stones for me to purchase. Both the inventory and Jack’s knowledge of the stones was extensive and high caliber. I only wish I had more time to learn and go through it all! I left feeling more than ecstatic about my new collection and was also amazed at the prices! I got way more than I had hoped with what I anticipated spending. I can’t voice enough how much I appreciate Jack and what he shared with me that day. My stones mean the world to me, and the experience of getting them was ever so special. Thank you! Thank you, Jack and Kathi! I look forward to getting to visit you again whenever I get out to Colorado next!!!

UPDATE: I got to have my second visit in October 2015. Jack had a fresh palate of the most amazing hematite sphere geodes and I got first pick! I made sure to save up money just for this visit and I am happy I did because I left with some of the most beautiful pieces! And I always adore how thoughtful Jack is in sharing his knowledge and excitement of stones. I am so grateful I came across this place and recommend it to everyone I know who lives in or is visiting Boulder. o o o

Jen |

Great selection. Knowledgeable and fair. No high markups. Bought items for young daughters and couldn’t be happier.

Todd |

Just got home and had a wonderful package waiting for me. I just got through unpacking it and looking at them. To say that the Charoite was stunning is an understatement. It is absolutely beautiful. I could go on an on about the other ones I received. You blew me away on everyone of them. You are no doubt the best person I have ever dealt with. You go the extra distance in helping. I cannot wait until my next order. Now, I think I will just sit back and fondle and look at them for awhile. Thanks again for the excellent quality products that you provide. Take care and will talk to you later.

Charlie | Texas

Im overwhelmed anytime I order from Kathi’s.. The stones are just out of this world. You can tell they’ve handpicked each one with care and attention to detail. I cannot overemphasize the quality of the stones they carry. Their delivery is incredibly fast, each stone is bubble wrapped and packed extremely well, and Kathi and Jack happen to be two of the friendliest, most accommodating people I’ve ever met. 12 out of 10 easily.

Taylor |

Great selection of crystals. Was quite stunned by the care for the crystals, something I have not seen in other shops. I had the pleasure of meeting, Jack was very knowledgeable on the crystals he presented. All around great place, not only for the crystals, but for the level of dedication to high quality service. I believe it to be the best crystal shop in Colorado

Jaden |

Jack and Kathi have quite an amazing collection in the basement of their home. (Call first to make an appt if you find this on Google Maps) Very friendly and informative about gems I had never seen before. The selection is the most comprehensive I have ever seen and I barely had time to scratch the surface. A must-see for any gem and mineral collector in Boulder.

Brandon |

The most unique and amazing stuff! Thank you so much for letting dad and I look at everything!

Amelia |

This was one of the best experiences I have ever had! I love rock shops, but I was blown away by the collection here and the personal attention from Jack. He sat with me for a couple hours, going through every variety I asked about. He was very patient and informative, and I have not stopped talking about the experience since I left there. I can’t wait to go back and get more. I can’t say enough about how lovely this was. Thank you thank you thank you! Also very affordable, which is great too.

Rallo |

The highest overall quality of rocks anywhere, at reasonable prices too. Every stone has been hand picked from larger collections, so your really seeing the top 1% of gem grade stones here.

Daniel |

Kathi and Jack were so accommodating to our unexpected visit (it’s best to call first!), and we got our own private viewing of the most beautiful collection of crystals I have ever seen! The energy of the room was very powerful. Andy and I are grateful for our conversation with Jack, and his wealth of knowledge about these rare and refined specimens. He also gifted us his book “How Not to Lose at Spades” which was just very cool. You’ve really got to see and experience Kathi’s Krystals, for a few pieces will also call to you, as they did to me.

Sarah |

Amazing specimens, run by amazing people. I only buy from Kathis.

William |

We went to Kathi’s Krystals for the first time to today, and were extremely grateful for the patience and hospitality we were shown. There was a large variety of beautiful crystals that had very reasonable prices. We would definitely go back to look at more crystals.

Christopher |

I have purchased stones for many years now from numerous places – in person and online and I have never had a memorable experience such as I did when I visited Jack and Kathi. The selection is amazing – they have some of the most beautiful stones I have ever seen. Jack spent time showing us everything we were interested in – and we were interested in alot! The prices are excellent, the customer service is exceptional and the stones are the highest quality I’ve ever seen. They have high expectations for stones and they don’t buy or sell anything less than the best. You will be amazed!

A Google User |

My friend Will and I had the distinct pleasure of spending our Saturday afternoon with Jack this past weekend. Aside from being the most unique rock shop I’ve ever been to, Jack and Kathi have the most extensive and diverse collection I’ve yet seen. Their passion for the stones and their dedication to selling the highest quality at the fairest prices are clearly evident. They carry a number of items that are not available anywhere else in the country, as well as more common stones. We spent two and a half hours perusing their collection and sharing stories with Jack and it was hands down the best rock buying experience I’ve ever had. I recommend Kathi’s Krystals without reservations and am confident I will be back time and time again.

Piper |

I could not have been more pleased with my experience at Kathi’s Krystals. They have the best selection of stones and crystals I’ve ever seen! I have shopped around many places in Denver for crystals but always walked away disappointed, not only with the selection, but with the customer service as well. I found Kathi’s Krystals when searching the best rock shops in Colorado and let me tell you, they should be number one. Jack took such phenomenal care showing us his selection for hours! The environment is so comfortable and organized, I can’t imagine anyone not finding what they were looking for with a smile on their face the whole time!

Taylor |

A terrific experience with Jack! Interested and interesting, plus a fabulous variety of stones. Such a pleasure.

Vast selection of exquisite stones. Jack and Kathi are welcoming and knowledgeable. If you’re looking for crystals this is the place!

Jessica |

Jack was soo nice and had the Best selection I’ve seen! The most impressive rock store we’ve been to! He was soo friendly and informative! We stayed longer than we were planning to because we just couldn’t bring ourselves to leave! 😉 lol … He also knew we were on a lil bit of a budget and he made sure we could take some home for our 4 kids as well! Thank you so much and we will definitely be back next time we are in CO!

Tina |

There’s not enough space for all the wonderful things I could say about this place!! I visited while I was in Colorado and I didn’t need to go anywhere else… Jack had everything. He had things I’d been looking for and hadn’t been able to find. Some of my absolute favorite crystals I own came from Jack! I’ll tell you a few; 2 pieces of GORGEOUS seraphinite, hand polished (I gave one to my husband and that’s his all time fav too).. The coolest agate EVER that’s an ENHYDRO!!! ?? A HUGE super 7 point, insanely divine lemurians.. Prehnite, covellite etc etc etc… I spent a few hours with Jack and could’ve stayed all day (if I didn’t have a ride outside patiently waiting ***thank u shanon!!??) There wasn’t anything Jack didn’t have and he knows what he’s got!! And ya best believe it’s top notch cus he is very particular and amazingly organized and clean and the best crystal steward I’ve met… If there’s something particular you might need, call Jack!!! He’s AWESOME!!! Thank you Jack for being YOU!!! I’ll be back regularly!!!!

Ginny |

My daughter and I visited from Kansas City. We spent close to 2 hours looking at the tremendous collection, learning from Jack and sharing stories. We walked away with a complete understanding for quality rocks, stones and the beginning of our collecting. The jewelry is stunning, Kathi has exquisite skill with wire wrapping and picking the perfect stone/gem for each piece. What a wonderful addition to our spiritual trip! This is truly a personalized experience, schedule your time so you can fully enjoy this spectacular collection.

Brenda | Kansas, City

Jack has ans excellent collection of rocks, knowledgeable and had a phenomenal sense of humour. I enjoyed my time at his place and when I am back in town he will be one of my first stops.

Gwen |

Absolutely amazing selection. Jack is one of the best labradorite dealers around. This shop is a true hidden gem!

Jaxx |

Wanted to let you know I received the palm stones. They are beautiful?? The pictures don’t do them justice. You have the best quality products that I have seen and will never hesitate to order from you. I’m sure you will be hearing from me again in the future. Thank you very much.

Charlie | Texas

This is a lovely little crystal gallery with quite an extensive selection of quality crystals, gems and stones. Jack was very accomodating in helping me find gifts for friends and family, as well as stones for wire wrapping jewelry. Located just a few blocks from Celestial Seasonings, you will need to call ahead and book an appointment in order to visit Jack and Kathi’s rock collection. Highly recommend~ A+

Lucas |

Where to begin… the stones themselves are of unreal quality, breathtaking is an appropriate adjective. I’m always stunned when I open a package from Kathi’s.. it’s easy to tell they hand pick each stone with care and attention to detail.. they also have a knack for finding specimens that no one else has. Their stones are extremely well packaged, their shipping is fast, and Kathi and Jack are just the friendliest, most accommodating people anyone could hope to meet. 5 stars is simply not enough… ???

Will | Texas

Of all the stone stores I’ve seen across America so far this is my favorite they have everything not kidding Lots of shapes and sizes Can’t wait to go back Jack was an amazing human being his story is tear jerking but beautiful all the same Had a blast keep up the good work guys !

Cody |

Their rocks and minerals and gems just blew me away…90 percent of what I saw I had never heard of and he did a great job helping us find really cool items on our budget so we could show our kids a wide array of rocks…thanks alot

Chris |

I had so much fun discovering beautiful, rare, interesting, and carefully chosen stones. I recommend a visit to any rock lover.

Victoria | Colorado

No need to go anywhere else! Jack is absolutely the best. More than knowledgeable, true wisdom, willing to share knowledge with out pretension. I was there once and feel I have made a friend I will be going back again and again. Don’t waste your time anywhere else, go see him. But make a appointment!

Robert | Colorado

What a refreshing experience. Jack and I sat down for at least an hour as he showed me incredible specimens I didn’t even know existed. It was such an informative experience as well. I learned, gawked, and eventually purchased a couple beautiful specimens. They have so much to choose from, and Jack was so ready to show me and tell me everything I needed to know and more. Will definitely be back soon.

Jack | Colorado

Oh my! This place is AMAZING! I recently visited my sister in Colorado and saw this was the place to go for high quality stones. Make sure you call ahead! We didn’t, but thankfully Jack was home.

Even though the store room seems small, just wait! The selection is never-ending. The knowledge is unmatched. The attention to detail for what you are looking for and for what you are needing is unparalleled. Before I left Colorado I was telling all of my friends back home. I will definitely be ordering in the future and coming back!

Lea | Ohio

I called with a question about fluorescent minerals and a busy day ahead of me but ended up spending over an hour in this wonderful shop. Jack’s great breadth of knowledge and willingness to share his passion for his trade and minerals made this the best rock shop experience I’ve ever had. Thanks again Jack ( :

Hunter | Colorado

Jack was very welcoming and personable. His love for gems and minerals was very inspiring. It’s easy to tell they have a passion for what they do and it is not treated as just a form of income. If you aren’t sure what your looking for they are a one stop shop with a huge variety and great quality.

Anthony | Colorado

This review is long over-do, but I still feel the same way. I went to Kathy’s Krystals right before valentines to give my bf a nice present since he is a geologist. I called Jack and he told me to come by right away. I found the house easy enough and was blown away by the mass selection of stones in their basement. Jack has an abundant amount of knowledge and you can tell he is very passionate about what he does. I got exactly what I was looking for and stayed within my budget. I would recommend checking them out if you have any idea what good quality is.

Nicole | Colorado

I got my tumbled gemstones today and I LOVE them all. You were right about the emeralds and the garnets. Very nice. The garnets are especially beautiful. I am glad you steered me in the right direction on those. I am very pleased with all of the stones that I ordered, but then I knew that I would be. As always your stones are exceptional. I’ll be back soon I am sure.

Betty | Idaho

Jack was very nice and hospitable. They have lots of material to view along with some rarities. I would enjoy visting again

My husband took me to see Jack for Mother’s Day, and boy oh boy were we pleasantly blown away! Never in my life have I seen such a collection! And the quality- and Jack’s knowledge. He definitely helped us find what we were looking for, and we walked out with a lot of amazing items! If you are looking for anything specific, crystals, rocks, spheres- whatever it may be, this should be your place to go! IT was fun and very informative and the personal time he takes with you- you do not experience that everywhere you go.. Thanks Jack!

Mendy |

Best part of my date night! It was an amazing experience to see that many beautiful and interesting rocks and minerals in one place. I felt welcomed from the moment I came in the door. Jack was funny and extremely knowledgable about everything in his collection. I learned so much. I will definitely go back! Thanks Jack.

Sophia | Colorado

Spending time with Jack at his home looking at some of the most beautiful rocks I have ever seen has been the most fun my girlfriend and I have had in a long time. The only thing more impressive than the wonderful selection of rocks was Jack’s knowledge of said rocks. We highly recommend this experience. Thank you Jack for being an awesome human being. We will surely be back to visit you.

Samuel | Colorado

I just left there and a I already wanna go back. This place will make a crystal junkie out of anyone. Amazing!!!!

Paula |

A story in every rock! They have a great eye for pretty stuff, rough and polished. Their rocks rock!

Jacob |

Wow! Two friends and I have been shopping for rocks for a couple years now. We have gone to many shops in multiple states. Kathi’s Krystals is definitely one of the best experiences we have had. The selection is awesome. Jack was so knowledgeable and shared his treasures with us. Some stones we were familiar with but many were new. All three of us made purchases during our first visit three weeks ago and will be returning in the next few days to pickup some stones we put on layaway when our stone selection exceeded our budget. I have a list of additional stones to look at this month so I’m sure I will be leaving with more for my collection. I highly recommend this home-based shop. In consideration of everyone’s time, please call for an appointment. I’m certain you will not be disappointed.

Pamela |

My parents gave each other heart rocks as a sign of their love. My father passed away 2 years ago. She has missedplaced hers. She was heartbroken My husband and I were visiting family in Denver. Decided to drive to Boulder for the day came across the website and called. SO GLAD WE DID!!!! THANK YOU FOR MAKING MY DAY!!!

Melody |

Great selection! Easy to lose track of time with thousands of stones and crystals to see, learn about, and purchase!

Kevin | Colorado

Me and my boyfriend were blown away by the amazing selection Jack and Kathi had. Jack had amazing knowledge of everything they had to sell and he explained to us everything he knew about our purchases. It was a great experience! I would advice anyone to go take a look! And we will definitely be back again!

Courtney |

Oh boy! First off the people are amazing. Jack has a keen eye for quality stones. I’ve never experienced anything like this shop, I highly recommend it if you’re ever in Boulder. Even if you’re not on Boulder, I suggest you go out of your way to arrive at Kathi’s Krystals, you won’t regret it!

Jon | Ohio

My eight year old grandson Max and I had an incredible experience at Kathi’s Krystals today. Max has recently become interested in rocks, and our two hours with Jack went above and beyond in helping to encourage his interest. Max brought his beginner collection, and Jack patiently identified them and gave background info, which was a learning time for both of us! He even showed us stones under UV light so we could see the magic that can be revealed. We came away with a bag of gorgeous rocks that Max picked out of thousands, which once again Jack spent time identifying (there ended up being 26 stones in all), and all this for only $9.00…incredible! We will be coming back next month for Max’s birthday, knowing we will have a wonderful time learning more about the world of rocks. Thank you Jack! Oh, and we really enjoyed meeting Okie, the family rescue dog…a total sweetie!

Terry | Washington

The collection is incredibly vast and the owner is friendly and knowledgeable. I would highly recommend this business, especially for people who are looking for a more authentic shopping experience or have questions about the rocks themselves

Heather | Colorado

Beautiful collection!! Very kind, warm owners! Highly recommend this shop.

Katie | Colorado

I can’t say enough about how wonderful our experience was with Jack and how amazing his collection is. I’ve spent time in other crystal shops, and Jack’s collection is in a completely different class. As many reviewers have indicated, we spent much more time and money here than we thought we were going to – time and money well-spent. Jack’s passion is contagious, and we now have a new hobby that we are crazy about! We were visiting Boulder, and this was one of the highlights of our trip. Making an appointment and spending time with Jack and his collection is a must. Thanks, Jack!

Dearest Jack and Kathi,

Thank you so much for opening your home and doing the work you do. What passion and knowledge you have for each individual stone. Your dedication to your work is so inspiring. I could feel the love in each piece you brought into your vast collection.

I have never seen such a collection… I was there for several hours, and barely made a dent… And you were there so willingly dedicating your time and knowledge. Truly a unique experience.

To anyone who is a lover of Crystals and Stones, I absolutely and Highly recommend this Bussiness, do not hesitate… I promise, you will not be disappointed. Not only are the pieces of the highest quality, but the pricing is beyond fair. There is no other place I would rather support

I am sitting in front of the stones I brought home… And am in love. I also was able to get some very special stones wire wrapped. Kathi, how amazing and gifted you are. Thank you, Thank you, Thank you. And continued blessings!

Christina | Washington

I was blown away by the incredible selection of beautiful stones Jack and Kathi had to offer, and even more so by the service and kindness I was welcomed with. I had not realized I needed to make an appointment until I was outside the front door. Jack greeted me with open arms despite having only about a minute’s notice that I was coming. He treated me like an old friend and was a pleasure to interact with. He helped me find the perfect affordable stones for my cousins’ Christmas gifts, and even threw in individual pouches for each stone at no additional cost. I will be back, and I will bring my friends. Thank you, Jack and Kathi!

Mallory |

Amazing experience! I took my nine year old grandson, and I was beyond impressed with all the one on one time Jack took educating him about rocks.

Terry |

Jack is so so kind. He has a great selection of rocks. He can help you find just the right thing. He is patient when you are indecisive. His prices are great. People come from other states to visit his shop. I’m so glad I found this place! I will always go back!!

Mackenzie | Colorado

Don’t let the location fool you. Jack and Kathi have a shop set up in their house and the selection was absolutely incredible and so well organized. Jack is extremely knowledgeable and friendly. We ended up staying for hours checking out everything and I still don’t feel like I saw half of what he had. We had a great time just talking with him. If you are looking for crystals Jack is your go to guy.

Kacee | Colorado

I’ve never seen such a unique selection of crystals and gems- and reasonable too! This shop is run right out of the home of the owners, so you’re really supporting small business here, and you won’t be disappointed 🙂 You can feel the grounding energy as soon as you step foot in their home, we even made good buddies with their dog! Jack really has a passion for crystals- we learned tons by hanging out and asking questions, even got to see crystals we’ve never heard of before. We will absolutely be making the trip from Denver to Boulder regularly to get more pieces. Thanks for the great hospitality, you have customers for life!

Darcy | Colorado

Had a very pleasant experience here. Jack was great! And their dog was even more delightful. Was awesome learning more about the different crystals while being grounded by such a loving dog at the same time. Really comfortable atmosphere and you’ll find anything you are looking for PLUS some. So glad we stopped by!

Alycia |

Wonderful experience. Very knowledgeable and friendly. I have never seen so many unique and beautiful gemstones.

Melissa |

What an amazing experience! My five year old son and I spent some time with Jack, and let me just say that he is insanely knowledgeable. I really enjoyed learning all he would tell me. You can tell this is his passion. Their stunning and rare specimens, the volume of inventory, and the relaxed and private buying experience all make Kathi’s Krystals unique and super special. I will be returning very soon. I learned so much, and my son had a great time too. Jack – you should teach informational classes for people who just want to learn more about crystals and gemstones! You are a wealth of knowledge, and it was a pleasure getting to know you. Thank you so much!

Allison | Colorado

Amazing selection with fair prices and very nice people. What more could you ask for?

Erik |

We were surprised to see an awesome selection of great quality stones and jewelry. Jack is so knowledgeable and generous with his time and expertise is this area. He educated my family and I on several different stones we have never seen or heard of. His price are fair but more importantly his selections are of superior quality. His wife Kathy makes very nice wired jewelry with the stones. If we ever visit Colorado again we will definitely have to visit them again and we will also make more time to spend with them. The 2 hours we were there was not enough to learn about all the beautiful stones and jewelry they had. I would highly recommend you visit the best little home store in Boulder Colorado.

Scott | Hawaii

I will echo what all the other reviewers have said: This was a great experience! Jack is so pleasant and knowledgeable! The selection is truly out of this world. You could spend HOURS looking at everything. Jack showed me some beautiful crystals that I never would have looked at and imparted tons of great information. No pushy sales stuff, just a great experience looking and learning! If I hadn’t stuck to the list I brought I could have bought everything I looked at. I will absolutely visit again soon! Oh, and Okie the Dog is just as friendly!

Jenna |

I came in here mainly wanting to get a sulfur crystals, not only did they have a beautiful selection of sulfur they where very inexpensive and to top it off I got it for half price! They had very beautiful spirit quartz for a very good deal, which was exiting because I have always wanted spirit quartz but it’s so expensive. The husband of Kathy was the one who helped us. He was so friendly and a very sweet kind hearted man. I had a very wonderful experience here and will definitely be returning. They have the cheapest high quality crystals I have found in Colorado.

Jake | Colorado

My daughter and I had the most amazing experience at Kathi’s Krystals! You will not find a more knowledgeable, warmhearted or passionate pair of shop owners, nor a better selection of superior quality crystals, stones and gorgeous handcrafted jewelry. We felt completely welcome to browse without being pressured or rushed. Jack was not only a walking encyclopedia on stones and their origins, but a passionate storyteller and just a kind soul. Kathi was so friendly as well, and the jewelry she makes is stunning! I cannot say enough about how positive our visit was. We are very pleased with the beauty of our stones, the more than reasonable price, and the rare treat of finding such wonderful people to learn and buy from. We will be back! Just a note: PLEASE CALL AHEAD and make an appointment to visit, so you can have the best experience with Kathi and Jack!

Shelby | Colorado

 

My boyfriend and I went to Kathi’s krystals and Kathi’s husband Jack was there to show us around. He was very educated about their rocks and had been collecting since he was 10 years old. All of their rocks are top quality. You can find things of all prices as well. Definitely recommend anyone to go there! Best rock selection in Boulder hands down. Just call first! 🙂

Marley | Colorado

Went to Kathi’s Krystals a few months ago with my boyfriend and we had a blast!! Jack was so helpful/knowledgeable and we found much more then we expected. We will definitely be coming back!!

Virginia | Colorado

I truly cannot say enough about what a joy it was to interact with this business. I have not met Kathi but I did meet Jack. It was not only an amazing experience because of his knowledge and the sheer amount and quality of the gems and stones and EVERYTHING they carry there. Both of these things would make you call this your favorite place to go when looking for these things. Over and above that was the warmth, the patience the kindness and the quality of person I met. I felt LUCKY that I found this place and met Jack. He not only knows his business like nobody I’ve seen, he is also so interesting, welcoming and everything is so relaxed. There was never an ounce of “push” to sell. Do yourself a favor and DO NOT pass this place up. Both personally and professionally they are pure class. With fair prices and an honesty I was blown away by. Do yourself a favor and schedule this visit!!!

Brian | California

Dear Jack and Kathi, Just wanted to send you a quick, but immeasurable thank you for letting us come see you and your “krystals” and more yesterday. Yes, we are thrilled with the new friends that we came home with… both expected and unexpected. And yes, we very much appreciate that you run your pricing structure through your kindness machine. But truly, it was wonderful to see you both and have an opportunity spend time chatting and exploring in a realm we are all passionate about (though of course, you two are quite a few levels of expertise above us). Certainly the whole experience was captivating for the eye and fascinating for the mind, but even beyond that our visit with you was also fantastic for our hearts. We’ll, look forward to seeing you again! Thanks so much!

Bram and Gretchen | Colorado

Jack was very accommodating to my spur-of-the-moment interest in stopping by. I left his place extremely happy with my purchases. I very much appreciate the time he spent with me discussing the background and attributes of his stones and crystals.

Sylvia | Colorado

Absolutely wonderful collection! Very intelligent and passionate collectors here in Boulder. If you are looking for a serious care taker of stones and crystals with a wealth of information then fhis is the best spot!

Zack | Colorado

We showed up without an appointment, not realizing the rock and crystal collection was in a residential neighborhood. We almost turned away, but I’m so glad we didn’t. After a quick chat with Jack on the phone, he came outside and led us into his home. We were blown away by an amazing collection of high quality stones and crystals. Personally, I’m drawn to the physical properties and geographic facts surrounding stones rather than the spiritual connection many have with crystals. Jack is a true collector, and I found it refreshing to hear what was important to me about the stones, instead of hypothetical healing properties. Jack was extremely friendly and personable. He showed us his personal collection, with some of his earliest crystals that he purchased at the age of 10. I would highly recommend visiting their shop, and we will definitely be back.

Brian | California

I can’t say enough good things about Jack and his shop! You’re supposed to make an appointment (we didn’t know), but Jack happily welcomed us into his home anyway. They have a wide variety of unique and very high quality crystals, minerals, and stones that I’ve never seen in other shops before. Jack is very knowledgeable and friendly, and was glad to educate us on the crystals. It was hard to choose, but we left with three pieces that we love and will enjoy for many years to come. Definitely do not pass up the chance to stop here – you’ll be happy you did. Thank you, Jack! Emily & David Morgan

David & Emily |

Best rock shop I ever been to and the best customer service out there bar none!

Joshua |

Place was AWESOME! Jack was a super cool guy and very passionate about what he does, loves to answer any questions you have. For us 3 time FLEW it felt like we could spend all day there! Very extensive collection with some very rare and unique pieces. Jack was super honest and taught us a lot. Overall an incredible experience! Thanks again Jack! Isaiah, Kelsey and Annette

Isaiah, Kelsey and Annette | Minnesota

Jack and kathi’s Crystal selection is amazing! I got a beautiful Crystal quartz with black tourmaline inclusions ring, and a chunk of selenite, calcite , and labadorite. The experience was great. I’m visiting from nyc and wanted to purchase some gifts for myself and of course I choose to add some gems to my beautiful collection. They have so many beautiful rare and unique gems. And the best part is the quality. When I held the crystals that called me I felt so much energy. Thanks Jack and kathy! I’m sure I’ll buy from you again especially when I move here in 2020!

David | Hawaii

Awesome!!! Wonderful experience! Jack is very knowledgeable. We just so happen to find a review of his shop as we were traveling from Tennessee. We spent four hours with him and he was just as friendly and enthusiastic after four hours as he was in the first 5 minutes. He spent so much time with our 14 year old rock hound daughter! He is a wealth of information and very fair with his prices. Would highly recommend a visit!

Valerie | Tennessee

We just spent nearly an hour looking at and purchasing some of the most beautiful stones and crystals I’ve ever seen. Very friendly and knowledgeable! Would highly recommend this place to anyone with an interest in crystals. One of boulders many hidden gems.

Geoffrey |

This place had amazing energy! Jack’s passion, love, knowledge, and genuine heart was an added bonus to his/her quality selection. Highly recommended

Nichole |

I was going to wait in the car…so glad I didn’t! Jack thoroughly explained and demonstrated each stone my daughter-in-law Nichole asked about…his knowledge and enthusiasm were infectious! Nichole is a healer and was overwhelmed by the energy in the room…I was by the beauty. Don’t be put off by the location…normally I wouldn’t want to go down in a basement to shop for anything. Jack’s was well-lit, comfortable and organized with everything readily available…actually preferable to a store-front. I am looking forward to the next visit and starting a collection!

Delin |

Had an amazing experience with Jack and Kathi! The stones are beautiful and well cared for and they have a huge selection. The quality of the stones and crystals are superior to anything you will find in a store and their prices are very fair. Jack has such a great passion for his stones and loves sharing his knowledge. Kathi’s jewelry is beautiful! I am very fortunate to live close by and I look forward to visiting again!

Alexis | Colorado

Wonderful atmosphere… Jack and Kathi are very knowledgable and passionate. I spent a little over 2 hours there and it felt like 30 minutes. Could spend a day there and still not see everything. Great people great place I would highly recommend checking them out

Devin |

Love this place! Spent hours chatting with the owner and going through Rocks. Great experience! Highly knowledgeable owners.

Katie |

Amazing place!

Min Sock | Colorado

Kathi’s Krystals provided what was possibly the best shopping experience I’ve ever had! This home-based shop offers top-quality gems and has a huge variety of rocks. Jack (Kathi’s husband) listened to my needs, asked relevant questions, and made helpful suggestions. He is very knowledgeable and passionate about gems and took lots of time to showcase various rocks and educate me on the industry. I can’t wait to visit again soon!

Ashley | CO

What a treat! I was looking for something special to get my two boys while I was traveling for work and I came across Jack and Kathi. I will cherish the time I spent with Jack, so knowledgeable. Thank you.

Zack | CA

Nice collection. Nice people

Prashant | India

Fantastic! Jack and Kathi are kind and welcoming, and they are obviously very passionate about their work. The quality and pricing is excellent, and you get a personalized experience. I will definitely return.

Sakura | Colorado

My brother and I had the pleasure of meeting Jack! The collection that they created over the years is nothing short of amazing! The couple operate from home so please, call ahead, something that we did not do! Jack is very knowledgeable on all the stones! We are both very happy with our stones and will be coming back! 🙂

Nina | Colorado

This home-based shop is amazing! Jack did a great job at showing us what we were looking for and many things we didn’t even know we would love. He was knowledgeable and had many things we had never seen before!! Wonderful find! We will shop from him again!!!

Samantha | Colorado

This was a wonderful experience. I had a lot of fun. I only wish that I had had more time to look around. If you’re planning on visiting give yourself more time than you think you will spend there. Although they business owners are not “into” the metaphysical aspect of crystals, they are truly knowledgeable about many rocks/crystals that are in their inventory. The prices are also reasonable for all budgets and they have quality pieces. I also learned a lot about different types of crystals that I have never seen before. I have recommend this place to several of my friends and will definitely be back in the future.

Mahea | Colorado

Kathi’s Krystals is an extraordinary home-based venue! We had such a pleasant experience learning about the materials and mining locations of each piece. Jack offers expert knowledge and inspiring stories – the entire shopping experience was one of a kind! We are extremely happy with our selections! Whether you’re just starting or you’re expanding your collection, you will find a wide variety of superior crystals/stones here! Thank you for everything, Jack – we will be back soon! P.S. Call ahead for an appointment and enjoy!

Brooke | Colorado

If you have kids who love crystals, plan time to take them here! Kid friendly; incredible collection at prices that need not reflect Pearl St Mall rents….wonderfully knowledgable and friendly proprietors! A hidden treasure!

Karen |

First rate selection. Very welcoming and exceptional prices

Krysta |

Really enjoyed our time going through all the samples and chatting with Jack. We definitely added some great pieces to our collection!

Alex | MO

An amazing experience through and through! The selection was amazing, huge, and you can tell they care a lot about giving you quality gems. So knowledgeable. This is their life- I will be back to support. Thanks so much you guys!

Aaliyah | CO

The moment I walked in, I was amazed! They have such a beautiful and wide variety of gems, minerals, stones, and crystals! I really enjoyed learning about the origins of the stones. You can tell their pieces are handpicked with care. I will most definitely be recommending them to other crystal lovers, and I will certainly be back.

Nina | CO

If you’re looking for the highest quality people with the highest quality crystals in Boulder, without the Boulder prices, you’ve found your new crystal home. I’ve been buying from Jack and Kathi for the last 3 years and there’s always something new to love. Jack is highly knowledgeable, helpful and beyond fair in his pricing. Thanks for the years of 10-star service!

Jack | CO

The owners of this home based business were super friendly and willing to show me each of the numerous stones on my list. Jack walked me through the different options in my price range so I found what I needed and stayed within my budget.

Christopher | CO

This is one of the best crystal shops I’ve been to. The owners are extremely knowledgeable and helpful, and I had a great experience!

Bari | CO

My friends and I had an incredible experience at Kathi’s Krystals. Jack (Kathi’s husband) knew so much about the rocks and crystals. He truly wanted to make our experience special. 2-3 other customers showed up while we were looking at the collections and he did such a great job juggling between us all making sure we had the best experience possible. I ended up buying a beautifully-made pendent made by Kathi herself. Also FYI, the shop is at their home. We were confused because we ended up in a residential area but just call if you get lost.

Alicia | CO

Folks reading this- you are in for a treat. Lots of surprises and a relaxed vibe to shop and talk rocks. Be courteous and call first! I got an amazing Celestite and a couple Spirit Amethyst quartz. and can’t wait to go back already!

Melanie | Cp

I can’t give anything less than a 5-star review! If there was a higher star rating, I’d give it. 2 days before Christmas and we were absolutely scrambling to get gifts like the procrastinators that we are. Jack gladly accommodated our search on Christmas Eve as we needed to find the perfect gift for a mum who absolutely loves and collects mineral stones. He took the time to show us everything he believed would be what we were looking for and, of course, in our price range. We couldn’t have been happier with our purchase and our experience. On top of that, the stone turned out to be absolutely perfect and loved by its recipient!! If someone is looking to just browse or actually buy stones, CALL JACK AND KATHI! They will do everything they can to make their clients happy. Off the charts recommendation!

Heather | CO

Wonderful afternoon spent looking and shopping for stones/ gems. Jack was very knowledgeable, welcoming and patient. The wrapped jewelry by Kathi is unbelievably beautiful, It was hard to choose one. Their collection is amazing! High quality pieces at reasonable prices. My 11 year old was hesitant to go, but Jack was so knowledgeable, she ended up loving it…. the sweet dog Oakie, was an added bonus!

Tia | CO

Incredibly knowledgeable people offering a unique and rare selection of both stones and jewelry. My 22 year old son and I received an interesting education and found meaningful keepsakes at reasonable prices

Forrest | CO

This was the absolute cutest shop! Love the variety of stones, plus the quality of them was impressive!! I bought a gorgeous rainbow moonstone necklace , labradorite and a seraphinite:)!

Tatiana | CO

They have the biggest selection I’ve ever seen. Both very friendly people and very wise in these precious rocks! Definitely coming again

Lorin | CO

Loved it! The energy of the wide variety of beautiful stones and crystals was amazing. ..and Jack was friendly, caring and very knowledgeable about the stones I was interested in. Kathi’s handmade crystal and wire pendants are obviously well-made and beautifully done. Highly recommend!

Penny | CO

Kathi’s Krystals is truly a gem! I came upon this shop in search for a specific type of crystal and walked out with others that felt more resonant. Having the time and space to gently connect (or not) with the crystals before purchasing them was just what I needed. Making an appointment over the phone was simple and when I got there Jack and Kathi were kind and generous with their time. They are passionate collectors and have an impressive selection of crystals. Their knowledge about the sources and current events related to the crystals was very helpful. Visiting Kathi’s Krystals is a precious experience.

Laurie | CO

The selection of crystals is beyond incredible. Owners are extremely knowledgeable and more than willing to tell you about every single rock that catches your eye, even if you have 1000 questions like I did. Would be a great place if you’re looking for an authentic gift for someone as these come at ALL price points. It’s practically impossible to leave without buying SOMETHING!

Kevin | CO

The customer service, knowledge about the different stones and crystals, and time spent helping us find exactly what we wanted and MORE was unmatched. I’d five it 6 stars if I could. Hands down the best rock shop in Boulder.

Katie | CO

Coolest crystal shop, biggest variety, nicest people. Really rare beautiful specimens and prices of every level. Knowledge is unparalleled and they also wrapped a stone for my necklace that’s immaculate and I love it.

Adam | CO

Hands down the best place for rocks and crystals in Colorado! Jack was super friendly and patient; we spent three hours looking through the huge selection. He was very knowledgeable and could answer any question we had for him, even down to where each piece came from. Definitely a new destination every time we come to Colorado!

Luke | OK

He had great quality and a great selection.

Brandon | Florida

Jack and Kathi along with their sweet dog are a gem. Their selection of crystals and stones are massive, ranging from palm stones, rocks, spheres of all sizes, and larger clusters. The best part is that you can sit on the floor and look through the thousands in their collection. There’s genuine conversation and inquiry in a comfortable setting to make the best selections. I was also really impressed with the quality of the stones and crystals. They do a really nice job of hand selecting their stones and crystals to sell. I for one will be using them as my go to purveyors of all things stones and crystals.

Michael | Colorado

What a wonderful place! Knowledgeable and super helpful and friendly owner. We bought some beautiful celestine. I would highly recommend checking them out!!!

Leonard Crystals & Jewelry | Colorado

Blown away by the selection! Jack and Kathy were very nice and we loved meeting Okie. I was more than happy with all of the beautiful pieces that were available and walked away with more than I had planned! Thank you both so much!

Cas | Colorado

Jack and Kathi are experts in their knowledge of crystals. They are always welcoming and have very high quality pieces. They know where every stone comes from and are generous and kind in their business and demeanor. Thank you for taking pride in your field and sharing your wisdom

Shawn | Colorado

Jack spent a lot of time with me picking out the perfect crystals for my new collection. The collection of masterpieces he had in stock were both beautiful and affordable. I will be back to have many more pieces of earths best artwork in my home. All the stones are natural and of the utmost beautiful quality! I was impressed by the selection available and the customer service delivered was unbeatable! Thank you for showing me your amazing collection and helping me start my journey!

Jean | Colorado

I was shocked at how many rocks and crystals were here. I could spend hours here! Don’t expect to stop by for just 10 minutes, there’s so much to learn and plenty more to look at!

Amanda | Colorado

Fantastic home based shop! Bigger variety than I’ve scene anywhere else. I live in Missouri but will definitely have to come back by the next time I’m in Boulder.

Mikaela | Missouri

I love this place! My name is Gus, I stumbled across this gem of a shop on accident. Jack the rock guy is so helpful and knowledgeable. This is definitely the place to go for a unique experience and amazing stone selection. I’m definitely going to be a repeat customer.

Augustina | Colorado

It was a real pleasure to view this extensive collection of crystals/stones and to interact with Jack and hear his knowledge of them. He had just what I was looking for and was very warm and welcoming. Highly recommend this place if you’re looking for high quality crystals/stones.

Brett | CO

My daughter and I happened onto this place after doing a Google search for crystals in Boulder. Jack, the owner showed us around and educated us on an amazing array of crystals. I will definitely be going back. The best selection of rocks and crystals!

Linda | CO

I was visiting Boulder with a friend and we both enjoy going to different towns in the area and checking out the local gem and mineral shops. Jack and Kathy’s collection of rocks is by far the finest collection I’ve ever seen. I spent over an hour and a half surrounded by some of the best pieces I’ve seen. They have prices you cannot beat, especially for the grade of product. Jack has been collecting for many years and his knowledge was delightful. I felt like I got a free lesson on gems and minerals. The experience was wonderful. Thanks Jack and Kathy! I will be back with friends.

Joshua | CO

This is the best place I have ever been for good quality, authentic stones. Jack and Kathi are extremely knowledgeable individuals that take hours of their time to hand pick everything in their shop. Every time I visited them, I left with a great deal of education and laughter. When you buy from this shop, you are buying pieces that are real, & that you will want to keep for a lifetime, all while supporting a family owned business. You will never have to worry about being scammed, or up-charged. Please take the time to check this place out and be ready for the ultimate level of awe. You’ve never seen a collection like this one. Plus, they have a cute dog!

Erin | Colorado

Jack was super kind and knowledgeable is all the stones he carries wish I would’ve gotten o meet kathi and their sweet dog , I was extremely impressed by the specimenns and the prices . Best rock shop in boulder & Denver !

Grace | Colorado

I was inspired by a fossilized coral piece that I traced back to Kathi’s Krystals. Will definitely visit whenever I’m in Boulder!!

Kishan | Colorado

One of the most amazing rock shops I’ve ever been to! Super sweet & friendly! They were more than happy to let me come by despite my short notice after I gave them a quick call. I got to learn tons about different types of minerals, where they’re from & how they form, as we all hung out on the floor looking through rocks for over 4 hours together while Jack happily told us all sorts of information about each stone that piqued our interest. It honestly felt like chatting with friends & family about everyone’s shared passion of rocks, despite only just having met them. If I didn’t have to eat, I could’ve easily stayed even longer to look and learn even more. I left with a hefty pouch of some of the loveliest and highest quality florite stones I’ve ever seen – well worth lightening my wallet for and none too expensive. Jack truly has a passion for these lovely rocks, so it was great to hang out and chat with him! I would absolutely drive 300+ miles to visit them again! This was honestly the highlight of our trip!

Clay | Texas

Absolutely lovely place! My friends and I spent over 4 hours looking and learning. We’ve seen specimens we’ve never seen anywhere else, and Jack told us tons of stuff! It was a real gem of an experience. I can’t wait to visit again next time I’m in Colorado, definitely made our trip.

Valil | Texas

Amazing! I had to take my kids with me and they were very patient with them and didn’t make me feel rushed. They have a very vast and beautiful collection!!!!

Kimberly | Colorado

I am grateful for the uniqueness of every visit at Kathi’s Krystals, just as unique as every crystal you see, admire, question, resonate with, and pick to gift to yourself or another. You may not always know where the crystal came from, yet you will always know where you got it from.

Jochem | Colorado

Great little shop in Boulder! Kathi’s wire wrapping is simple yet elegant and much more appealing than most wire wrapping artists in my opinion! Great shop for agates, jasper, palm stones and more! Keep an eye out, Jack may have a few quartz clusters for sale/on display that I dug and prepared myself! Thanks again!

Van Cleave’s Minerals & Gems | Colorado

What an amazing collection of beautiful rocks and crystals! Jack is so fun to talk with and has a wealth of knowledge about the rocks and where they came from. It was fun to see how some of the rocks glow under his black light, and other light sources, so cool! Very personalized service and great shopping experience. I can really tell the owners have a lot love for what they do and appreciate their customers. I will definitely be coming back

Michele | Colorado

Exactly what my wife Nancy was looking for: knowledgable, friendly people with a great selection of beautiful crystals and stones. Nancy has been trying to find a source for translucent, semi precious stones she uses to make gorgeous table lamps. We along with a couple of friends just spent several amazingly entertaining hours with Jack while he showed Nancy his selection. We met Kathi and Okie and had a wonderful time, and Nancy left with a beautiful bunch of stones perfect for her craft. We can’t recommend this business too highly. You will not be disappointed

John | South Dakota

If you are a rock or crystal fan, this place is a must-stop if you are traveling to boulder-Denver area. Kathi’s Krystal’s has a surprisingly nice selection of gem stones and many sizes of most. The quality was so good that it made it difficult to choose which stones I liked the best out of each lot. Jack was very knowledgeable and prices were very fair. It was also nice that they offered easy shipping for larger items as I was traveling. The selection and quality bested most retail storefront rock shops I have visited and was very unexpected from a home-based set up.

What a FANTASTIC experience to purchase my crystals from Jack and Kathi. Jack has EXTENSIVE knowledge about the crystals, and shares that knowledge eagerly and readily, drawing you into a world – his world – that you really had no idea was so broad and interesting! He has fantastic stories and gives you either the space you need to choose your crystals, or the insight and knowledge you may need to help make that decision. And what an amazing, extensive collection of so many different types of beautiful crystals! They are high quality, individually chosen by them. I would recommend, without hesitation, purchasing from Kathi”s Krystals!

This place is an absolute gem! Truly refreshing to have met such genuine and passionate people. They have some of the most beautiful authentic crystals/ stones I have ever seen and at such a fair price. Also, ask about the jewelry- some of the finest hand crafted wire wrapped crystal work I have ever seen. 10/10 would recommend and I will absolutely be coming back!

This was by far the best crystal shop experience I have ever had. As an avid international traveler, I’ve been to shops all over the world. Jack is incredibly knowledgeable and personable- answering all of my questions, taking the time to show me different pieces and point out their unique qualities. Hours flew by chatting. I learned so much! Jack was even kind enough to meet me at the bus stop so I wouldn’t get lost on the way to their home. Jack makes you feel at home, and it’s a really amazing experience to take your time, learning about the pieces, looking at each piece in a very calm and peaceful setting. It’s like you’re hanging out and chatting about rocks with your friend. I would highly highly recommend Kathi’s Krystals! I know I will be back 🙂

My fianc and I just visited Kathis Crystals for the first time ever. You HAVE to go here! Top tier selection and variety that you will not find anywhere else. We have been to a huge variety of crystal shops in several states and nowhere can touch the quality and selection of rocks you will find here. Jack was phenomenal! He was incredibly knowledgeable and was able to find all kinds of crystals he knew we would be interested in. He was gracious, helpful, and gave us great deals. We stayed for two and a half hours only because we were in a rush. Otherwise, we could have easily stayed MUCH longer. This will be a staple shop to visit every time we come to Colorado! Thank you!!!

Friendly people, we went just as things began opening up from Covid-19 and Jack helped us through the selection and made sure everything was as safe as possible. Awesome collection.

If you have any interest in rocks this is 100% worth the stop. Jack will spend time making sure all your questions are answered which is very rare to find. He is super knowledgeable and kind. Don’t let the residential area dissuade you, this was the best part of any trip I have taken. I can only say good things about my experience.

Its a pleasure doing business with him. If you’re looking for quality pieces, look no further Jack and Kathy are your people! Thanks Jack, looking forward to many more transactions!

Everytime I come to Boulder I must stop at Kathis Krystals, Jack is a great guy who is very knowledgeable about all of his inventory. I recommend it to anyone who wants to buy Crystals!

First time Gem buyer and the experience of seeing the massive selection along with knowledge gained blows every stop and go shop away. You will surely gain something leaving Kathi’s.

We loved meeting Jack and getting to see his vast inventory of high-quality minerals! Easily the highest quality mineral seller in the Denver/Boulder area!! Every rock has a history, a mine that it originated from and details that are unique to that individual mineral. Jack displayed the fluorescent minerals I was purchasing under a black light (ruby in kyanite and pink calcite), he offered me trays of genuine enhydro agates and I couldn’t resist! I had to buy one! Jack was knowledgeable and hospitable during the shopping experience and every crystal coming home with me felt like a perfect match! Jack’s wife, Kathi, is a skilled jewelry artist! I purchased a beautiful wire-wrapped multi-colored tigers eye ring that fits perfectly and has a beautiful flash. I used my new beautiful stones for recent social media posts and they have all received great reviews! I plan on many more trips for more beautiful stones!!
