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.

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.
