Rainbow Fluorite Sphere
Fluorite · Semi-Precious Gemstone and Mineral Specimen

Crystal System
Cubic (Isometric), typically forms cubes, octahedrons, or massive aggregates, polished into a sphere shape here
Mineral Group
Halides
Chemical Formula
CaF2
Formation Process
Hydrothermal deposition in low-to-medium temperature veins, often associated with metallic ores like lead and zinc
About This Crystal
A polished spherical specimen displaying translucent to transparent properties with banded zones of pale green, purple, and white colors, exhibiting a smooth, vitreous luster
Physical Characteristics
Color varies with multi-colored bands of purple and green, white streak, perfect octahedral cleavage in four directions, conchoidal to uneven fracture, specific gravity of 3.18, brittle tenacity, famous for strong fluorescence under UV light
Optical Properties
Isotropic, singly refractive, refractive index of approximately 1.434, no pleochroism due to cubic crystal system
Hardness & Durability
Origin Region
China, Mexico, South Africa, USA, UK; found in hydrothermal veins and sedimentary deposits
Hardness & Durability
Mohs hardness of 4, low toughness and easily scratched, sensitive to thermal shock and harsh acids, requires careful wear if used in jewelry
Care & Maintenance
Clean with warm soapy water only, avoid ultrasonic or steam cleaners, store separately to prevent scratching by harder stones like quartz, avoid prolonged direct sunlight to prevent fading
Rarity & Value
Common mineral, though high-grade banded multicolored material carved into large spheres or objects can vary moderately in price based on color saturation, transparency, and size
Special Characteristics
Strong fluorescence under ultraviolet light (often blue or violet), distinct color banding and zoning visible throughout the polished sphere
Lore & History
Historically carved into ornamental vases and objects since ancient Roman times due to its softness and beauty; in modern crystal healing, it is associated with mental clarity, focus, and balancing the third eye and heart chakras, though these are traditional beliefs rather than scientific claims
