Physical properties

Hardness: 5.5-6.5; Color: Rosy-pink to brownish-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 metamorphic rocks and hydrothermal deposits. Often associated with manganese ores and contact metamorphism environments.

Uses & applications

Used primarily as an ornamental stone, in jewelry (cabochons), and as a minor ore of manganese. Frequently carved into decorative objects like this crystal tower.

Geological facts

Rhodonite was the official state gemstone of Massachusetts, designated in 1979. Its name comes from the Greek word 'rhodos', meaning rose.

Field identification & locations

Identify by its distinct pink color contrasted with black dendritic (tree-like) or veiny patterns of manganese oxide. Found in Russia (Ural Mountains), Australia, Brazil, and the USA.
