Rhodochrosite is a manganese carbonate mineral with chemical composition MnCO 3.In its pure form (rare), it is typically a rose-red colour, [5] but it can also be shades of pink to pale brown.
It is commonly found as radiating clusters of acicular needle-like crystals in cavities in sulfide rich limestone and dolomite or in geodes.
