Physical properties

Hardness: 5.5-6.5 on Mohs scale; Color: Rose-red, pink, often with black dendrites or veins of manganese oxide; Luster: Vitreous to pearly; Crystal System: Triclinic; Cleavage: Perfect in two directions; Specific Gravity: 3.4-3.7

Formation & geological history

Forms in metamorphic environments, specifically in manganese-rich deposits altered by regional or contact metamorphism.

Uses & applications

Used primarily as an ornamental stone, for tumbled stones, cabochons, carved objects, and occasionally as a minor ore of manganese.

Geological facts

Rhodonite derives its name from the Greek word 'rhodos', meaning rosy, in reference to its characteristic pinkish-red color. The distinctive black inclusions are typically manganese oxide.

Field identification & locations

Easily identified by its unique combination of vibrant pink/red body color paired with stark black dendritic veins. Commonly sourced from Russia, Australia, Sweden, and the USA.
