Found a beautiful opal at a great price. I was not disappointed when it arrived. Even better in person.

I love the quality, presentation and the price of the stones. I love the identification card - report they send with each stone.

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