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.

GemSelect offers excellent choices, prices & service- highly recommended! Unfortunately, prior to ordering a replacement gemstone, my jeweler neglected to mention it needed to be one that was a'cushion cuta' to fit the existing mount. Have yet to return/exchangea'
