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

I always enjoy the selection and the unique cuts I can find here. I would love to see more hex cuts tho! Maybe some rose cuts too!

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.

I searched for the size, dimensions and quality of the stones I was looking for and then compared and ordered.

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.
