Rhodonite is a pink manganese silicate mineral of variable composition that often contains significant amounts of iron magnesium and calcium. It has a generalized chemical composition of MnFeMgCaSiO 3. Rhodonite is often associated with black manganese oxides which may occur as dendrites fracture-fillings or matrix within the specimen.
