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!

They have a wonderful selection of gems of all sorts, shapes, cuts, and quality. I am very particular about the quality of stones I buy, and found many with VVS clarity and excellent cut and polish. I am thrilled with each of the stones I purchased, and would definitely recommend GemSelect to everyone.
