Green Fluorite
Fluorite · Semi-Precious Gemstone and Mineral Specimen
Crystal System
Cubic (Isometric)
Mineral Group
Halides
Chemical Formula
CaF2
Formation Process
Hydrothermal processes, crystallizing from mineral-rich solutions in veins and cavities at low to moderate temperatures.
About This Crystal
A tumbled, smooth, and polished green stone showing translucent to transparent qualities with subtle internal zoning and feather-like inclusions typical of fluorite.
Physical Characteristics
Color ranges from light to deep green with white banding/zones; white streak; perfect octahedral cleavage in four directions; conchoidal to uneven fracture; specific gravity around 3.18; brittle tenacity; often exhibits strong blue or violet fluorescence under UV light.
Optical Properties
Singly refractive; isotropic; refractive index of approximately 1.434; weak or absent pleochroism due to isometric crystal system.
Hardness & Durability
Origin Region
China, Mexico, South Africa, USA, UK; typically found in hydrothermal veins and associated with metallic ores.
Hardness & Durability
Mohs hardness of 4; poor toughness due to perfect cleavage; sensitive to thermal shock and harsh chemicals; low wearability for daily-wear rings.
Care & Maintenance
Clean gently with warm soapy water; avoid ultrasonic and steam cleaners, harsh acids, and prolonged direct sunlight to prevent fading; store separately to avoid scratching by harder stones.
Rarity & Value
Common; value depends on color saturation, transparency, size, and crystal perfection; generally affordable for tumbled and common specimens.
Special Characteristics
Often exhibits strong fluorescence under ultraviolet light; beautiful internal color banding.
Lore & History
Historically used for carving and ornamentation; in modern metaphysical practices, green fluorite is associated with the heart chakra, mental clarity, and clearing negative energy.
