Green Fluorite
Fluorite · Semi-Precious Gemstone and Mineral Specimen
Crystal System
Cubic (Isometric), typically forms cubes, octahedrons, and massive or tumbled habits
Mineral Group
Halides
Chemical Formula
CaF2
Formation Process
Hydrothermal processes, crystallizing from mineral-rich water solutions in veins and cavities at low to moderate temperatures
About This Crystal
A tumbled, smooth specimen of translucent to transparent green fluorite displaying characteristic light and dark green color banding, with a vitreous luster
Physical Characteristics
Green body color, white streak, perfect octahedral cleavage in four directions, uneven to conchoidal fracture, specific gravity of 3.18, brittle tenacity, often exhibits strong blue or violet fluorescence under UV light
Optical Properties
Isotropic, singly refractive, refractive index of approximately 1.434, no pleochroism due to the cubic crystal system
Hardness & Durability
Origin Region
Found globally with notable deposits in China, Mexico, South Africa, UK, and the USA; forms in hydrothermal veins
Hardness & Durability
Mohs hardness of 4 (reference mineral for fluorite), very low toughness and soft, highly sensitive to thermal shock and scratches, poor wearability for daily-wear jewelry
Care & Maintenance
Clean gently with warm soapy water only; avoid ultrasonic cleaners, steam, harsh chemicals, and prolonged direct sunlight to prevent fading
Rarity & Value
Common mineral, readily available as tumbled stones and mineral specimens; low to moderate value depending on clarity, size, and color intensity
Special Characteristics
Often exhibits strong fluorescence under ultraviolet light, and occasionally thermoluminescence or triboluminescence
Lore & History
Historically used for ornamental carvings due to its softness and vibrant colors; in modern metaphysical practices, green fluorite is traditionally associated with the heart chakra, mental clarity, and clearing negative energy
