Kathi's Krystals

By far the best and most authentic crystal shop I have ever been to. It's a lovely couple running the shop out of their basement and you can clearly see the love and passion behind this store. The vibrational energy in this store is something I've never experienced in any crystal shop before I will definitely be going back :)

I had such a great time at this rock shop. Kathi and Jack run the shop out of their house and it makes the experience even better. They are some of the sweetest people I have ever met, and their dog Okie is super cute too! There is a very large selection of crystals (polished and raw), and you’re guaranteed to find something that stands out to you in whatever price range you are looking for. Jack is so knowledgeable and will answer any questions you have. Kathi also makes some cool art with the crystals on her Etsy! There was so much to see I could’ve stayed there for hours, so I will definitely be coming back! Oh, and don’t forget to ask for the Okie show!

My fiancé and I were headed back from Estes Park, and I had missed stopping into the rock shops in the area, glad I did. This was a magical place and such a wonderful experience. Jack was very welcoming and gave great insight and details into each piece we loved!! Thank you so much we are looking forward to our pieces and can’t wait to share your site with everyone I know that loves stones- and if there is ever an item you are searching for they likely have it. ♥♥

I just bought stones from Kathi's Krystals for all my Christmas gifts. Jake helped me search for stones for specific people keeping my budget in mind. He was kind, patient, helpful and informative! I usually get stones from brick and mortar stores but this was a much less stressful and more personal experience. I did not go crazy with Christmas presents this year but I wanted to get something special for people to represent their own individuality as well as my relationship to them. I would highly recommend Kathis Krystals to anyone interested in buying stones and crystals!

Jack was extremely friendly, knowledgeable and gave (by far) the best experience I’ve ever had while shopping for crystals and rocks. His collection was way bigger than I had expected and the quality was amazing. I will only be shopping with him from now on. HIGHLY RECOMMEND!

We stumbled upon Kathi's krystals and Jack and had the most wonderful experience! We walked away with some incredible crystals! Jack was incredibly knowledgable and answered all of our questions! Plus we loved the dog show afterwards!! Go see Jack!

Absolutely would recommend Kathis Krystals as the best place to find beautiful rocks of all types. Jack is kind, accomodating in the extreme and obviously loves what he does. We basically spent an hour plus together ooh’ing and ahh’ing different beautiful pieces, and at no point did he try to rush or pressure any sale. This isn’t a touristy rock shop, this is a passion project with owners who really care about the quality of their stock and your experience finding your perfect gems. I feel great about my purchases, and my kids are over the moon with the bags of tumbled rocks i brought home for them too. Thank you Jack, I had so much fun and will for sure be back soon.

If you are looking for unique rocks and crystals that you've never seen before, go check out Kathi's Krystals. I have never seen a collection so visually stunning and extensive. There is a wide range of selection that is bound to catch your eye. Jack, the owner, is very personable and knowledgeable. I enjoyed learning about each rock that peaked my interest and getting to know its background. The entire collection is of the highest quality I have ever seen. I can't forget to mention how reasonable the pricing is as well. Many other sellers and stores are very overprice for rocks that are fairly regular and basic. Jack sells the most gorgeous collection at a very fair price. Overall, I throughly enjoyed my experience and my purchases exceeded my expectations in every way. I recommend buying here instead of any other rock and crystal store I have been to. 5/5 stars!

Amazing experience coming here, so glad we did. Jack is so pleasant, very knowledgeable, and has a huge collection. His collection was beautiful but my favorite part was just talking to Jack and learning so much about rocks that I never knew. To make things even better, when we were finished shopping we got the special Okie show featuring their adorable doggo. Couldn't recommend any more!

From the moment we stepped into Kathy's Krystals, it was clear we were in for a unique and enriching experience. The warm welcome we received from Jack and his incredible pupper set the tone for what was to become a memorable visit.

Jack's knowledge about stones and crystals is profound. He shared insights and information with a passion that's both engaging and educational. Whether you're a seasoned collector or a curious newcomer to the world of crystals, Jack's expertise will illuminate your understanding and deepen your appreciation for these natural wonders.

But it's not just the knowledge that makes Kathy's Krystals stand out; it's the energy. There's something truly special about the ambiance of this place. It's as if the crystals themselves contribute to an atmosphere of calm and positivity that envelops you the moment you walk in. This energy, combined with the friendly company of Jack and his furry companion, creates an environment that's not just a store but a sanctuary.

Our experience at Kathy's Krystals was nothing short of amazing. It's a place where you can truly feel the care and passion for what they offer. We left not only with beautiful crystals but with a sense of upliftment and calm that stayed with us long after.

Luis and I are already looking forward to our next visit to Kathy's Krystals. For anyone interested in crystals, or simply in search of a positive, enriching experience, we can't recommend it highly enough. Jack and his amazing pupper have created not just a business, but a community hub that welcomes everyone with open arms and good vibes.

100/10⭐⭐⭐⭐⭐ (I hope you like puns)

If you're looking for rocks, minerals, and people who are precious themselves, look no further. Each time we visit Jack is always so patient and informative, we leave with priceless information and gems. The content and quality is beyond amazing both in the rocks and minerals they sell and in the friendly and informative owners. 💎 Really, we feel so spoiled seeing such awesome hand picked treats Jack has to offer that we never miss a chance to drop by if we're in Colorado. Honestly makes the 8 hour trip worth it. A gem of our trip, if you're a little anxious or have a hard time socializing, don't worry! They're incredibly kind and pleasant. Just give them a ring to make an appointment, I promise it's well worth it! We've spent hours enjoying every minute here.

Go for the gems, but stay for the Okie Show. 🐾 Okie is the most precious gem there.🐶♥

Amazing. Simply amazing. They run their massive shop out of their home and they were so incredibly hospitable. I will absolutely return and refer every gem lover to them. This was very fun and very educational. I got some beautiful pieces I didn’t even know existed and I’m thrilled to add them to my collection! Thank you so much for your time and energy. Even though I did call late on a Sunday. You all still opened your home to me and allowed me time within your space. Thank you so much

Jack and Kathi should charge admission just to view their amazing collection! Better than going to the Museum of Nature and Science's Gems and Minerals Hall! Jack was interesting and patient as my son and I browsed the rocks and minerals. Learned a lot! Will be returning soon!

Where do I begin! This was such a heart warming and amazing experience. Jack is such an amazing and beautiful person. His knowledge and passion for his crystals are astounding. You can tell he truly cares about every piece he has in his shop. The collection was so beautiful! I was mesmerized the moment he opened the door! Jack is incredibly honest and knowledgable on all his pieces. He took the time to bubble wrap all our pieces we bought! You truly need to check this store out, I promise every part of it will be well worth your time. I feel so blessed to have found this shop and to have met Jack. To top it all off, my boyfriend and I were blessed to witness the Okie show! His adorable doggo juggling! It was such a heart warming experience. Hands down, my best crystal shop experience!

This place is amazing! Jack was super friendly and helpful. Found a perfect pair of earrings for a gift to my love. Most beautiful wire wrapping I have seen. This place is a gem.

Don’t miss the Okie show!

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!

What an amazing find in Boulder, CO!! Stumbled upon Jack's shop through a google search, and all the 5 star reviews live up their ratings. Jack is extremely knowledgeable and passionate about what he sells and collects. The quality of his crystals were superb and many are rare and difficult to find. I found this beautiful cactus quartz, also known as spirit amethyst, my favorite in my collection thus far. I will definitely be visiting Jack again on my next trip to Boulder. Thanks Jack!

Best crystal selection (by far!) we’ve found. And Jack is great and knows his rocks. Definitely go visit. Hundreds (thousands) more crystals than they show online.

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! 🙏🎩

Kathi's Krystal Store is a gem-lover's paradise. Whether you're seeking a crystal for healing, meditation, or simply to adorn your space, this store offers a plethora of options and a delightful shopping experience. I left the store with a newfound appreciation for the beauty and energy of crystals, and I'll definitely be returning to expand my collection. Highly recommended for anyone looking to explore the world of crystals and all the magic they have to offer.
