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'

My experience has always been fantastic. Today I saved 6 gems to email a customer looking for a particular color blend to fit into an east west setting, so her options were limited, but we found one she wanted, deleted all the others in the cart and order the gem she selected. It was helpful to be able to put them in the cart so I could save them until she selected the one she wanted without having to research all of them again.

Absolutely love the website, selection and products. Can you guys add a gemstones with inclusions tab. I like those it'd be nice to have them all in one place but i do understand it would be alot of work to go through and categorize them. Thank you anyways
