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

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.
