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.

Found a beautiful opal at a great price. I was not disappointed when it arrived. Even better in person.

The site provided lots of detail, factual data, and good photos. I also like the availability of searching by price range as well as by the type of stone.

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'
