I have purchased stones from gem select in the past and have been very satisfied. I expect to repeat that experience with this purchase as well

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.
