Notes - One of the rarest stones on earth. Heavily opaque stones of little color are almost worthless. The more transparent or higher colored stones can get very, very pricey. Ocean blue.

The few specimens that we have are not perfect clarity (nor are they being sold for a fortune per carat) but they have very good translucency and good to excellent color, making them very expensive, normally. A good price would be 1000.00 a carat. This is quite a deal
