Physical properties
Hardness: 5.5-6.5 on Mohs scale; Color: Rose-pink to brownish-red with black manganese oxide inclusions; Luster: Vitreous to pearly; Crystal structure: Triclinic; Cleavage: Perfect in two directions; Specific gravity: 3.5-3.7
Formation & geological history
Forms in metamorphic rocks or as a result of hydrothermal activity in manganese-rich environments. Common in ore deposits with galena and sphalerite.
Uses & applications
Primarily used as an ornamental stone, for lapidary work, jewelry (beads, cabochons), and as a minor ore of manganese.
Geological facts
The name Rhodonite is derived from the Greek word 'rhodos', meaning rosy. It was once used in Russia to decorate the interiors of palaces and cathedrals.
Field identification & locations
Identify by its distinctive 'rose' pink color paired with black dendritic or veiny manganese oxide patterns. Commonly found in Russia, Sweden, Australia, Canada, and the USA (New Jersey).
