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'

Would have bought an indigo and selenite, but neither listed. But, you do offer quite a large assortment otherwise.

Loved the price and the quality and the certification options which is the main reason why I buy. The guarantee is also a great reason to use gem select.
