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!

I did not realize these stones were of jewelry quality. They are really beautiful, just not what I was expecting which was more of a natural stone.
