Overall Rating -> 10 
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'

Easy picking, fast checkout, secure shipping. Cana't ask for anything more than efficiency and a good price.
