Site is easy to navigate - details on cut, polish, and finish work and techniques were helpful. 3d view or wireframe diagram of stones would be nice.

Nice website I just don't know much about the quality until I receive the stone.

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.

I love Gem Select! When you order what you see is what you get. As soon as you make payment that particular gem is taken off the photo album. That way the one you select is a one of that kind.
