First time using this website. It was both exciting finding things in my price range and things Iam gonna save up for and use in other pieces. I love that the picture of the gem is the exact gem I'll be buying. I haven't tested the gems yes but they said they sold me 100% natural gems.

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.
