I love the quality, presentation and the price of the stones. I love the identification card - report they send with each stone.

All these questions, and I don't have to give any blood. What a Deal... I absolutely enjoy the Gem Select emails every month. This one today was special. I always say, I'll know it when I see it. This stone today was the One. Odd and Intriguing. Thank You So Much for all that you do.

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.

I am never let down by GemSelect. I love that you get the exact stone you want. Shipping is always in a few days. I have spread the word about GemSelect on social media jewelry creating groups that I attend. This sapphire is going to make one gorgeous ring
