The citrine gems are beautiful. I appreciated that each stone was individually shown on the website so I could see exactly what I was getting. No mystery person selecting random stones for me. The documentation included with each gem was high quality as well. Great price and arrived as expected.

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

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.
