Rhodonite, a manganese, iron, and calcium silicate, (Mn,Fe,Ca)SiO3, in some cases forms the primary source of very important deposits of manganese oxides, such as the manganese ores of India. Rhodonite often has black manganese oxide veins running through a specimen, giving it the distinct appearance of pink with black crisscrossing lines and flower-like formations throughout. These are the forms most commonly used as gemstones, especially in beads an
d ornamental objects. Rhodonite gets its color when a mineral is formed in deposits of manganese or ore veins.The presence of manganese in the rhodonite structure causes characteristic color of this stone– mostly, rose-red or brownish red. The stone received its name due to such a color – from the Greek word “rhodon” meaning “rose”.
