Polished rhodonite

Rhodonite, (Mn,Fe,Mg,Ca)SiO₃; commonly mixed with manganese oxides and other minerals

AI-generated identification · may be incorrect

Pink to rose-red material with dark brown-black manganese-oxide patches, polished vitreous-to-greasy luster, and uneven mottling. Rhodonite has triclinic crystals and Mohs hardness about 5.5–6.5; this appears to be a shaped, polished specimen rather than a natural crystal face.

Physical properties

Formation & geological history

Forms mainly through metamorphism or hydrothermal alteration of manganese-rich rocks, often in manganese deposits; specimens occur in rocks of many geological ages.

Uses & applications

Used for cabochons, beads, carvings, and ornamental objects; also collected as a decorative mineral. It is generally too soft and cleavable for everyday ring wear.

Geological facts

Dark veining or patches are commonly manganese oxides and contrast with rhodonite’s characteristic pink color.

Field identification & locations

Identify by its pink body color with dark manganese-oxide markings and moderate hardness; common sources include Russia, Australia, Sweden, Peru, and the United States. The photo supports a rhodonite identification, though visual identification alone cannot confirm composition.
