The site provided lots of detail, factual data, and good photos. I also like the availability of searching by price range as well as by the type of stone.

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

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.
