I visited several online loose stone shops trying to find rare stones. I finally found one that I've been looking for here, and very satisfied. Looking forward to receive the item in 3 weeks.

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.
