Loved the price and the quality and the certification options which is the main reason why I buy. The guarantee is also a great reason to use gem select.

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!
