Hauerite - Sold

Hauerite is a manganese sulfide mineral related to pyrite. Haidinger (1846) named the mineral in honor of Joseph Ritter von Hauer (1778-1863), and his son Franz Ritter von Hauer (1822-1899), both Austrian geologists. This is a loose octahedral crystal, more than 90% complete, found in clay. One corner of the octahedron is missing. This is nevertheless a difficult mineral to obtain, and due to its modest size, it carries a modest price for such a collectible rarity.
