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.

Easy picking, fast checkout, secure shipping. Cana't ask for anything more than efficiency and a good price.
