Client 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!

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!

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

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.

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!

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!

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.

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

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!

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!!!!

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!

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.

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!

 

Jennifer | Iowa



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!

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.

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.

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!

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

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?

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!

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!

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!

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.

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

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

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!

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

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

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.
