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.

I liked the selection of gems, and price. I did not like your PayPal process. I already have a PP account and you want me to sign up for another.

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'
