Overall Rating -> 10 star ratings

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 trust this company to deliver exactly what is offered. I have never had to return a selection of Gems. I appreciate the company's detailed description of their product. It helps this customer find mounts before the gems arrive. Any day of the year one can find a wide selection of gems, be it by price, color, cut, lot or single. Pricing does not jump all over the place and stays reasonable. Be assured your items will arrive in perfect condition as the company's shipping department does a great job.
