Rhodonite is a manganese inosilicate and member of the pyroxenoid group of minerals, crystallizing in the triclinic system. It commonly occurs as cleavable to compact masses with a rose-red color often tending to brown because of surface oxidation. Rhodonite crystals often have a thick tabular habit, but are rare. It has a perfect, prismatic cleavage , almost at right angles. The manganese is often partly replaced by iron, magnesium, calcium and sometimes zinc, which may sometimes be present in considerable amounts; a greyish-brown variety containing as much as 20% of calcium oxide is called bustamite; fowlerite is a zinciferous variety containing 7% of zinc oxide.
