Mooreite - Sold

Mooreite is a magnesium manganese zinc sulfate originally found at Sterling Hill. Bauer & Berman (1929) named the mineral in honor of Gideon P. Moore (1842-1895), chemist at the New Jersey Zinc Company. In this example, mooreite forms a platy growth up to 4 mm thick covering a fracture in willemite-franklinite ore. There is a prominent pearly cleavage 2.5 cm across on the surface of this specimen, but the whole surface is actually covered in mooreite. This is a good representation of the mineral.
