I needed a very specific color of tourmaline and Gem Select had it. I had to get the client to agree and then ordered the stone. It arrived better than pictured and we all were very happy.

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.

On the clarity options it goes "and better" so if youre looking for si specifically and you click si and better it still shows you basically everything. It just removes the opaques. Itd be nice if it was vs only, vss only, si only, etc

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 purchased 4 gemstones in different sizes to be able to make a family ring for my granddaughter. I got exactly what I saw and they are absolutely beautiful! Shipping was quick compared to other gem stores I have dealt with! I will definitely order more stones from your company, as I am a collector and have several stones. You are my new go to company in the future
