All items were delivered on time with all items meeting or exceeding my expectations. Cut, clarity and color were very close to the photos and description.

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'
