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.

The site provided lots of detail, factual data, and good photos. I also like the availability of searching by price range as well as by the type of stone.
