I needed a very specific color of tourmaline and Gem Select had it. I had to get the client to agree and then ordered the stone. It arrived better than pictured and we all were very happy.

I was looking for high-quality amethyst on this site, and I was able to compare size, color, and weight in detail before making a purchase.

No problems. I had a minor address issue in the past and someone got back to me very quickly and we resolved the issue satisfactorily. I appreciated the quick, concerned response. So important when buyer/seller are so far apart in distance. Thank you Gem Select. Keep up the good work!

I had a very easy time navigating the web page and using filters to find what I was looking for. The varied selection was nice to see and pricing is clear and fair.
