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

Gem Select has a user friendly website and the product is very good as is the price. The gems are described accurately and I always get what I think I'm getting.

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.

It's mostly good, only some item's are easier to find through the search than the menu

I was looking for a site with every type of gem I could want for setting in luxury blades and assumed I would need to look outside the US, but GemSelect made it easy to get everything I wanted without leaving the house! Wide enough selection that I do not feel the need to look elsewhere and pricing the same.
