Singly refractive or uniaxial positive with a low birefringence of 0.009; vitreous to waxy luster; no significant pleochroism in the massive zones
Hardness & Durability
Origin Region
Brazil, Madagascar, South Africa, and India; commonly formed in volcanic rock cavities or hydrothermal veins
Hardness & Durability
Mohs hardness of 7; good durability for display, but brittle and sensitive to high impact or sudden thermal shock
Care & Maintenance
Clean with warm soapy water and a soft cloth; avoid ultrasonic cleaners, harsh chemicals, and prolonged exposure to direct sunlight which can cause the purple color to fade
