Formula: (Mn2+,Fe2+,Mg,Ca)SiO3

Rhodonite is a manganese inosilicate and a member of the pyroxenoid group.

Hardness: 5.5- 6.5

Specific Gravity: 3.4-3.7

Luster: Vitreous

Color: Rose pink to brownish red, gray or yellow

Streak: White

Common with the pink rhodonite are black manganese oxides.

It used to be mined in India as a source of manganese. Today, it is mined primarily as a lapidary mineral and mineral specimens.

Rhodonite is usually found in metamorphic rocks associated with other manganese minerals. It is also found in rocks that have been altered by contact metamorphisim, hydrothermal and metasomatic processes. It is usually massive to granular in occurrence with crystals being rare.

It is the state gem of Massachusetts.
