    0%

    Dravite is a relatively common form of Tourmaline commonly referred to as “Brown Tourmaline”.

    Dravite can be found in localities such as Dobrova, Dravograd, Slovenia where some spectacular museum grade pieces have been found.

    I acquired this specimen from Greg at Blue Gems at the August 2016 Sydney Crystal Show.
