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.

Would have bought an indigo and selenite, but neither listed. But, you do offer quite a large assortment otherwise.
