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 have shopped at Gemselect for nearly 20 years. I especially like that you see pictures of the exact gem you are purchasing. You are a trusted source.

I've purchased things from GemSelect before. What you see is what you get, which is not always the case with gem sites online. You can find some good value with gem select, and I will buy from them again.

I found the filter options excellent. Yours was the third site I visited (asked chat got for reputable online sellers of loose gems) and the first I purchased from as I was able to easily find what I was looking for.
