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

I have been buying gems for several years off and on and love their selection and great low prices. I started out wanting to get an example of each type of gem but after looking at all the types of gems and reading about them I realize it is almost impossible for me to do. It took me years just to read about them all. Gem Select is the best gem site you can find. For information or to buy. Steve M.

Easy picking, fast checkout, secure shipping. Cana't ask for anything more than efficiency and a good price.
