Physical properties

Formation & geological history

Formed in metamorphic rocks, specifically in manganese-rich ores or hydrothermal deposits. Geologically, it can variation in age but is often associated with regional metamorphism of sedimentary manganese-rich rocks.

Uses & applications

Used primarily as an ornamental stone, in jewelry (cabochons and beads), and as a minor ore of manganese. Also highly popular among crystal collectors.

Geological facts

Known as the 'Stone of Compassion,' it was once used in Russia to line the sarcophagi of Tsars. The name is derived from the Greek word 'rhodon,' meaning rose.

Field identification & locations

Identify by its distinct 'bubblegum' pink color paired with black manganese oxide veins. It is commonly found in Russia, Sweden, Australia, and the USA (notably New Jersey and Massachusetts). High density helps distinguish it from pink quartz.
