Overall the site is good to use and simple to navigate for what i needed and i liked that they are clear and detailed on the size shape and cut of the stones only input id like is for stones that have a specific refractive quality like moonstone in my case if theyd showcase the cut stones refraction so you know how it looks when buying

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.

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
