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!

Site worked well and helped me find a rock that matched what I was looking for. Well within budget and I trust it will show up, so that's definitely positive. Not much else to it. Satisfied.
