The problem
Commercial stones are cut to weigh the most, not to look the best.
Rough goes to whoever can keep the most carats out of it, because carats are what a price list pays for. What comes back is heavy, a little dull, and shaped to drop into a calibrated setting, because that is exactly what it was cut to do.
We cut for the stone. Sometimes that costs weight to keep the color even, and sometimes it produces a shape no calibrated setting will take. That is not a problem here, because we are designing the piece around it anyway.
The plan
Three steps, and you can stop at any of them.
You do not need to arrive knowing what you want. Most people start by pointing at a color.
One
Choose a stone.
Start in the collection. 3,655 stones are in the case today, across 32 species, so there is room to find the exact green or the exact blue rather than the one the case happened to have. Open the collection.
Two
Tell us what you want.
What you would wear every day, what you would never wear, the metal, the size, the budget. We come back with what is possible and what it will cost, before anything is made. Start a design.
Three
We cut it, and it gets made.
Kag cuts the stone here, in house. The piece is then made in small batches with the independent Thai artisans we have worked with for years. You see the stone before it is set. How that actually works.
Or take one that exists
If one of the finished pieces is already the one.
There are finished pieces in the case below, made the same way, and they ship now. We make them in small editions rather than production runs, so most of them exist exactly once: 118 of the 137 in the collection today. If one is already the piece, take it. If it is close, it is a good place to start a design from. See what is ready to ship.

Honestly, I'm not sure where to start! I met David and team at a gem show and was initially attracted to their wide selection of loose stones, I'm so glad I stopped to look! The CG team has been amazing to work with. Their collections are STUNNING and their many years in the business and family connections allow them to bring the finest products in at good prices, and they are happy to share their knowledge and expertise. I've purchased pieces in several forms – loose, preset and custom set – all were perfection. I confidently recommend Caveman Gems to anyone looking for 'that something special'.12/10 stars.

We were so impressed with the quality and the service we received. My old engagement ring had been lost by another jeweler, and we came to them looking for the perfect sapphire and they not only helped us with that but helped us to design a beautiful ring that is now my new engagement ring. We love it so much and we are very thankful for all they did.They also did a very detailed appraisal of my new ring and another ring. Everything was above and beyond what I hoped for. I highly recommend them (and have already recommended them to friends.)

We had the greatest experience with Lo and the team. We met at our favorite winery and viewed some beautiful pieces and loose gems. We purchased 2 rings that evening and a loose stone which was then set by their jeweler. Reasonable prices and very satisfied with their awesome customer service. Friendly and amazing staff that was very in tune with our needs. Highly recommend Caveman Gems!

I purchased jewelry from Caveman Gems and I’m beyond impressed! The craftsmanship is absolutely beautiful , you can tell each piece is selected with care and attention to detail. The quality is excellent, and the designs are unique yet timeless. I’ve received so many compliments every time I wear them. The customer service was excellent! They were friendly, responsive, and professional throughout the entire process. My order arrived quickly and beautifully packaged. I highly recommend Caveman Gems. I’ll definitely be coming back for more!

What one of one means
Made once, and not made again.
When one sells, it is gone. We do not reorder it, because the stone it was built around was cut once and there is not a second one sitting in a drawer somewhere.
That is true of the finished pieces, and it is the reason a custom piece works at all. The stone is the part that cannot be repeated. Everything we design around it inherits that.
Tell us what you are looking for. We will show you what we have and what we could make, and we will say so if the answer is no.
Or book a call instead.
