Fluorite - Natural minerals and crystals

Fluorite is a mineral belonging to the halide class. It is mainly composed of calcium fluoride and crystallizes in the cubic system. fluorite crystals are cubic or octahedral, although other shapes can be observed. This mineral is known for its variety of colors, ranging from transparent to purple, blue, green, yellow and pink. fluorite typically forms in low-temperature hydrothermal environments, often associated with other minerals such as calcite, barite, and galena. fluorite is used as a flux in metallurgy, as a fluorinating agent in the production of aluminum, and in the manufacture of glass and enamel. fluorite is also a source of fluorine used in many industrial processes. fluorite has a hardness of 4. It is soluble in strong acids and fluoresces under ultraviolet rays. The density of fluorite varies slightly depending on its composition. The properties of fluorite make it a mineral of interest for research, particularly in mineralogy, crystallography and geochemistry.
