Description

Combo featuring thin crystals of pyrrhotite intermixed with a couple of large brassy chalcopyrite crystals, associated to milky quartz and pitch black grainy sphalerite.
Quite scarce and sought-after material, as the mine is dismissed since decades. The material is exposed through etching due to a gangue of thick carbonates.
Pyrrhotite is very friable, therefore do account for some specks to detach during shipping.
