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.
