About This Crystal
Translucent to cloudy pink stone with a vitreous luster. This specimen is a tumbled pebble showing internal fractures and a milky transparency.
Physical Characteristics
Pink body color, white streak, no cleavage, conchoidal fracture, 2.65 specific gravity, non-fluorescent (usually)
Optical Properties
Refractive index 1.544-1.553, low birefringence, uniaxial positive, may show asterism/tyndall scattering
Hardness & Durability
Origin Region
Brazil (Minas Gerais), Madagascar, South Africa, and the United States (South Dakota)
Hardness & Durability
Mohs hardness 7.0; good toughness though internal fractures can cause fragility; excellent for jewelry
Care & Maintenance
Clean with warm soapy water; avoid prolonged exposure to direct sunlight as it may cause the pink color to fade
Rarity & Value
Common; value depends on color depth and transparency; larger clear pieces are more valuable; often untreated
Special Characteristics
Tyndall scattering effect creates its characteristic 'milky' look; can rarely show a six-rayed star (asterism) when cut into spheres
Lore & History
Historically used in Roman and Egyptian seals; traditionally known as the 'Stone of Unconditional Love' associated with the Heart Chakra
