Dravite from May Downs Station, Mt Isa QLD

Dravite is a relatively common form of Tourmaline, often called “Brown Tourmaline”.

Dravite can be found in localities around the world including areas 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.
