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!
