Rhodonite

Rhodonite (MnSiO₃), a manganese inosilicate

AI-generated identification · may be incorrect

Typically pink to rose-red with black manganese-oxide veining; vitreous to pearly luster, triclinic crystals, imperfect cleavage, Mohs hardness 5.5–6.5, and specific gravity about 3.4–3.7. The specimen appears tumbled or roughly polished.

Physical properties

Formation & geological history

Forms mainly in manganese-rich metamorphic rocks through hydrothermal or metamorphic processes, commonly during Precambrian geological events. Important deposits occur in Russia, Australia, Brazil, Peru, South Africa, and the United States.

Uses & applications

Used as an ornamental stone, carving material, cabochon, bead, and lapidary rough; historically, manganese minerals including rhodonite have had limited metallurgical importance.

Geological facts

Its characteristic black markings are manganese oxides such as pyrolusite, distinguishing many specimens from similarly colored pink minerals. Fine translucent rhodonite is prized for jewelry and sculpture.

Field identification & locations

Identify it by its saturated rose-pink color, black dendritic or massive veining, moderate hardness, and relatively high density; test cautiously because it can resemble pink calcite or rhodochrosite. Commonly collected from manganese deposits and metamorphic terrains.
