Green Fluorite
Fluorite · Semi-Precious Gemstone and Mineral Specimen
Crystal System
Cubic (Isometric) system, forming cubes, octahedra, or massive/granular habits
Mineral Group
Halides
Chemical Formula
CaF2
Formation Process
Hydrothermal processes in low- to high-temperature veins, often associated with metallic ore minerals like lead and zinc
About This Crystal
A translucent, pale to sea-green raw crystalline fragment with a vitreous luster, smooth worn edges, and internal fracture lines typical of tumbled or naturally weathered mineral specimens.
Physical Characteristics
Color ranges from pale green to deep emerald green, white streak, perfect octahedral cleavage in four directions, conchoidal to uneven fracture, specific gravity of 3.18, and frequently exhibits strong blue or violet fluorescence under UV light.
Optical Properties
Singly refractive, isotropic with a low refractive index of approximately 1.434, typically exhibits no pleochroism.
Hardness & Durability
Origin Region
Found worldwide including China, Mexico, South Africa, UK, and the USA; forms in hydrothermal veins
Hardness & Durability
Mohs hardness of 4, making it soft and easily scratched. It has poor toughness due to perfect cleavage, requiring careful handling for jewelry use.
Care & Maintenance
Clean gently with warm soapy water. Avoid ultrasonic cleaners, steam, harsh chemicals, prolonged exposure to direct sunlight to prevent fading, and protect from harder minerals that can scratch it.
Rarity & Value
Common to uncommon depending on clarity and color intensity; affordable in raw and tumbled forms, widely available for collectors.
Special Characteristics
Famous for strong fluorescence under ultraviolet light, thermoluminescence, and triboluminescence.
Lore & History
Historically carved into ornamental vases and objects since antiquity. In modern crystal healing, green fluorite is traditionally associated with the Heart Chakra, believed to clear negative energy and bring emotional balance.
