Formation & geological history

Forms in manganese-rich metamorphic rocks or hydrothermal replacement deposits. It is typically found in regional or contact metamorphic zones often associated with other manganese minerals.

Uses & applications

Used primarily as an ornamental stone, in jewelry (cabochons and beads), and as a minor ore of manganese. Frequently used for carvings and decorative objects.

Geological facts

The name is derived from the Greek word 'rhodon', meaning rose. It was once believed to help travelers and was often gifted to them for protection.

Field identification & locations

Identify by its distinct 'rose' pink color and the presence of black dendritic or swirling veins of manganese oxide. Found in Russia, Sweden, Australia, Canada, and the USA.
