Rhodonite-bearing rock

Rhodonite (MnSiO₃), likely in a manganese-rich matrix; visual identification is uncertain

AI-generated identification · may be incorrect

Rhodonite is typically pink to reddish with black manganese-oxide veining, vitreous to pearly luster, triclinic crystals, Mohs hardness 5.5–6.5, and specific gravity about 3.5–3.7. The pictured rough specimen has pale pink-white and dark reddish-brown areas; those colors alone do not confirm the identification.

Physical properties

Formation & geological history

Forms mainly in metamorphosed manganese-rich sedimentary deposits and hydrothermal veins. Such deposits occur across a wide range of geological ages.

Uses & applications

Used as an ornamental and carving stone, in beads and jewelry, and as a collector specimen; manganese ores have industrial uses, though rhodonite itself is not usually an important ore.

Geological facts

Rhodonite’s name comes from the Greek rhodon, meaning “rose,” referring to its characteristic pink color.

Field identification & locations

Look for pink-to-red material crossed by black manganese-oxide veins; distinguish it from jasper by its mineral cleavage and typically denser appearance. Found in places including Sweden, Russia, Australia, Japan, and the United States.
