Physical properties
Hardness: 5.5-6.5 on Mohs scale; Color: Pink to rose-red with black manganese oxide veins; Luster: Vitreous to pearly; Crystal structure: Triclinic; Specific gravity: 3.5-3.7
Formation & geological history
Formed in manganese-rich ores and metamorphic rocks, as well as hydrothermal veins and replacement deposits. It is often a primary mineral in regional metamorphism.
Uses & applications
Used primarily as an ornamental stone, for lapidary work like beads, cabochons, carvings, and occasionally as a minor ore of manganese.
Geological facts
The name comes from the Greek word 'rhodos', meaning rose. It was once believed to help foster brotherly love and emotional healing.
Field identification & locations
Identify by its characteristic pink color and high hardness compared to rhodochrosite. Common locations include Russia (Urals), Australia, Brazil, and the USA (New Jersey).
