Dravite

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.

It can at times be hard to make an exact distinction between the minerals dravite and uvite.
