Hydrothermal processes in low to moderate temperature veins, often associated with metallic ore deposits.
About This Crystal
The prominent sphere features distinct purple, green, and white color banding with a polished, glossy finish, displaying translucent to semi-transparent optical clarity.
Physical Characteristics
Varies in color including purple, green, blue, yellow, and clear. White streak, perfect octahedral cleavage, uneven or conchoidal fracture, specific gravity of approximately 3.18, brittle tenacity, and often exhibits strong fluorescence under UV light.
Optical Properties
Isotropic optical character, single refraction, refractive index of approximately 1.434.
Hardness & Durability
Origin Region
Worldwide, notable deposits in China, Mexico, South Africa, and the United States. Forms primarily in hydrothermal veins.
Hardness & Durability
Mohs hardness of 4, low toughness with easy cleavage making it sensitive to impacts and not ideal for everyday jewelry wear.
Care & Maintenance
Clean with mild soap and warm water, avoid harsh chemicals and ultrasonic cleaners, store separately to prevent scratching by harder minerals, and keep out of prolonged direct sunlight to prevent color fading.
Rarity & Value
Common to uncommon depending on color and clarity, widely accessible as tumbled stones, spheres, and mineral specimens, with price largely dependent on size, color saturation, and banding quality.
Special Characteristics
Strong fluorescence under ultraviolet light, distinct color zoning, and perfect cleavage planes.
Lore & History
Historically used for carving ornamental objects due to its softness and vibrant colors. In modern metaphysical practices, it is traditionally associated with mental clarity, focus, and balancing the third eye chakra, though these remain traditional beliefs rather than scientific claims.
