I liked the selection of gems, and price. I did not like your PayPal process. I already have a PP account and you want me to sign up for another.

I've purchased things from GemSelect before. What you see is what you get, which is not always the case with gem sites online. You can find some good value with gem select, and I will buy from them again.

Found a beautiful opal at a great price. I was not disappointed when it arrived. Even better in person.

I did not realize these stones were of jewelry quality. They are really beautiful, just not what I was expecting which was more of a natural stone.
