Braunite (Braunite II) with Andradite


Braunite is a manganese oxide / silicate mineral with tetragonal symmetry. Haidinger (1828) named the mineral after Kammerrath Braun of Gotha, Germany. Moore & Araki (1976) studied braunite, confirmed its tetragonal symmetry, and showed a relationship with bixbyite. De Villiers (1980) showed that some braunite crystals have a doubled unit cell, and these are different from the original braunite. This is such a specimen, known as Braunite II, with striated steep pyramidal crystals to 6 mm, overlain partly by orange-red andradite crystals. Attractive. This specimen ships with a Clive Queit label.
