I really liked the email, and the link that help return me to the site. I didnt have access to my card info while checking out and I had to put my phone away so I lost the tab. Fortunately, since I did give an email- they sent me a link that brought me back to where I was. Greatly appreciated

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.
