Zircon from Mud Tank Zircon Field, Harts Ranges NT
Zircon is a natural mineral found in a very small area in the central part of Australia, a remote area called the Mud Tank Zircon Field located on Alcoota Station, Northern Territory.
One side of this has been polished which gives it the greasy lustre. A nice touch to the specimen.
I acquired this specimen from Tony at Mineral Store Australia at the August 2016 Sydney Crystal Show.

The dark brown colour seen in most Zircon crystals is caused from iron oxide impurities.
