Fluorite is a mineral with a veritable bouquet of brilliant colors. Fluorite is well known and prized for its glassy luster and rich variety of colors. The range of common colors for fluorite starting from the hallmark color purple, then blue, green, yellow, colorless, brown, pink, black and reddish orange is amazing and is only rivaled in ...
Fluorite is the only mineral for which significant quantities of the important element fluorine can be obtained. Fluorite is also used as a flux in the manufacture of steel and other metals to eliminate impurities. There is a great demand for Fluorite in the optics field, and to meet it synthetic crystals are grown to produce special lenses.

Deposits of minable fluorite exist in the United States; however, nearly all of the fluorite consumed in the United States is imported. The primary countries that supplied fluorite to the United States in 2011 were China, Mexico, Mongolia, and South Africa. All of this fluorite is imported because production costs in the United States are so high that the material can be produced in these other countries and shipped directly to customers in the United States at a lower cost.
In 2011 several companies were producing and selling synthetic fluorite as a byproduct of their phosphoric acid production, petroleum processing, or uranium processing activities. A limestone producer in Illinois was also recovering and selling small amounts of fluorite from their quarry. That company is developing an underground mine to exploit a large vein of fluorite which they hope will be in production in 2013.
Fluorite is a form of calcium fluorite and belongs to the Halide family of minerals. Fluorite boasts a transparent crystalline structure with a vitreous luster. It forms in well formed isometric cubes, clusters, nodules or massive forms. Fluorite is hailed as the most colorful crystals in the world.
Mineral Characteristics. Fluorite, or fluorspar, is a mineral composed of calcium and fluorine. As an allochromatic mineral, fluorite is colorless in its purest form. However, natural processes during its formation produce different colors. Fluorite stones typically have color zones, but some change colors entirely. Color changing fluorite is ...
