Hausmannite - Sold

Hausmannite is a double oxide of manganese, with a distorted spinel crystal structure. Unlike traditional spinel group minerals, hausmannite has tetragonal symmetry. While known for decades, it was Haidinger (1827) who named this species after Professor Johan Friedrich Ludwig Hausmann (1782-1859), at the University of Göttingen, Germany.

Hausmannite here forms pseudo-octahedral crystals to 7 mm on edge in a cavity in white baryte. Not often seen form the type locality. This specimen was part of the Charles Trantham (1936-2020) estate and an A. Lang label accompanies this specimen.
