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!

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.

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.

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.
