Uniaxial positive; refractive index of 1.544-1.553; birefringence of 0.009; doubly refractive
Hardness & Durability
Origin Region
Global distribution; notable sources include Brazil, Madagascar, USA, and the Alps
Hardness & Durability
Mohs hardness of 7; good durability and toughness, making it highly suitable for jewelry and handling
Care & Maintenance
Durable and easy to clean; can be washed with warm soapy water; avoid harsh hydrofluoric acid; safe from standard household wear
Rarity & Value
Very common; low to moderate monetary value depending on clarity and size; widely used in jewelry and lapidary arts
Special Characteristics
Exhibits piezoelectric and pyroelectric properties; often contains microscopic fluid inclusions or minor fractures causing internal light scattering
Lore & History
