Have made 2 purchases so far from GemSelect and they have been amazing! Anytime I requested additional info, videos or pictures of a particular item, the response was always timely and helpful. This is a great place to buy, if you are looking for loose stones. Highly recommend!

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!
