Physical properties

Hardness: 7-7.5 (Mohs scale), Color: Rose-pink to purplish-red, Luster: Vitreous, Crystal Structure: Isometric, Cleavage: Indistinct, Specific Gravity: 3.84

Formation & geological history

Metamorphic formation in schists or igneous environments as an accessory mineral. Formed under high temperature and pressure conditions within the Earth's crust.

Uses & applications

Primarily used as a gemstone in jewelry (rings, earrings, necklaces); also used as an industrial abrasive in lower grades.

Geological facts

The name is derived from the Greek word 'rhodon' meaning rose. Unlike many garnets, rhodolite is prized specifically for its lack of brown or orange undertones.

Field identification & locations

Identified by its signature pinkish-purple hue and lack of pleochroism. Commonly found in Tanzania, Sri Lanka, and North Carolina, USA. Collectors look for high clarity and saturated 'raspberry' color.
