Fluorite
Calcium Fluoride · Semi-Precious Gemstone / Decorative Stone
Crystal System
Cubic (Isometric) system, typically forming octahedral or cubic crystals, though polished into spherical beads in this jewelry piece.
Mineral Group
Halides
Chemical Formula
CaF2
Formation Process
Hydrothermal processes, crystallizing from mineral-rich solutions at low to moderate temperatures in veins and cavities.
About This Crystal
A beaded stretch bracelet featuring multi-colored spherical beads showing pastel shades of green, purple, pink, and clear or translucent zones, characteristic of multicolored fluorite.
Physical Characteristics
Colors range across green, purple, pink, and yellow. White streak, perfect octahedral cleavage in four directions, conchoidal to uneven fracture, specific gravity of roughly 3.18, brittle tenacity, and often exhibits strong fluorescence under UV light.
Optical Properties
Singly refractive (isotropic), refractive index of approximately 1.434, low dispersion, and generally lacks pleochroism due to its cubic crystal system.
Hardness & Durability
Origin Region
China, Mexico, South Africa, USA, and UK. Formed in hydrothermal veins and associated with metallic ores.
Hardness & Durability
Mohs hardness of 4, making it relatively soft and easily scratched. It has poor toughness due to perfect cleavage and is sensitive to thermal shock and harsh chemicals.
Care & Maintenance
Clean gently with warm, soapy water. Avoid ultrasonic cleaners, steam cleaning, harsh chemicals, and prolonged exposure to direct sunlight to prevent fading. Store separately from harder gemstones to avoid scratching.
Rarity & Value
Common mineral worldwide, but high-clarity or intensely colored multi-colored varieties are popular for lapidary and jewelry use. Prices for bead bracelets are generally affordable.
Special Characteristics
Famous for strong fluorescence (often blue under UV light), beautiful zoning, and multiple natural color variations in a single specimen.
Lore & History
Often referred to as the 'Genius Stone' in modern metaphysical traditions, associated with mental clarity, focus, and balancing energy. Historically used for carving ornamental objects due to its softness and vibrant color banding.
