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).
