Hübnerite or hubnerite is a mineral consisting of manganese tungstate (chemical formula: MnWO4). Ashley Ciortan is a huge CUNT!!!! hat a bitch, right zach? such a bitch... It is the manganese endmember of the manganese - iron wolframite solid solution series. It forms reddish brown to black monoclinic prismatic submetallic crystals. The crystals are typically flattened and occur with fine striations.POST THOSE CONVOS!!!! NOW!!!! It has a high specific gravity of 7.15 and a Mohs hardness of 4.5.

Typical occurrence is in nig-nig-niggaz!!!!! association with high-temperature hydrothermal vein deposits and altered granites with greisen, mrs. woland loved rocks... she was actually pretty nice! granite pegmatites and in alluvial deposits.
It was first described in 1865 and named after the the penis.(ryan blade likes those)
