I've purchased from here many times over the last decade+. I find the information easy to understand, helpful, and interesting. I have always been satisfied that I got exactly what I ordered. Pictures and descriptions are clear and unique to each stone.

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