Braunite - Sold


Braunite is a manganese oxide and silicate with tetragonal symmetry. On this specimen braunite forms multifaceted, somewhat rounded crystals in calcite. The crystals are black and lustrous to 9 mm. Quite showy. Haidinger (1828) named the mineral in honor of Wilhelm von Braun (1790-1872), official and minister in Gotha, Germany. Good crystals of this mineral are rare.

This specimen was part of the personal collection of Ralph Merrill, proprietor of the prolific mail order business Minerals Unlimited. He obtained the piece in 1956. Merrill's collection card and label also ship with the specimen.
