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.

this site is awesome. I was able to look at the products think about purchasing and come back and find the same products. With the amount of inventory gem select has. Its awesome to be able to filter the way that they allow you too.

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