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.

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'

I was looking for high-quality amethyst on this site, and I was able to compare size, color, and weight in detail before making a purchase.
