Green Fluorite Cluster 1

Fluorite is the mineral form of calcium fluoride, CaF₂. It belongs to the halide minerals. It crystallises in isometric cubic habit, although octahedral and more complex isometric forms are not uncommon. The Mohs scale of mineral hardness, based on scratch hardness comparison, defines value 4 as fluorite. Fluorite is deposited in veins by hydrothermal processes, and is also found in the fractures and cavities of some limestones and dolomites. It is a very common rock-forming mineral found in many parts of the world. In the mining industry, fluorite is often called “fluorspar.”
