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.

Easy picking, fast checkout, secure shipping. Cana't ask for anything more than efficiency and a good price.

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

Gem Select has a user friendly website and the product is very good as is the price. The gems are described accurately and I always get what I think I'm getting.

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.
