Fluorite

Fluorite is the most abundant fluorine-bearing mineral that occurs as cubes or compact masses.

Chemical Formula: CaF2
Other names: Calcium fluoride
Layman's explanation: Fluorite is a transparent to translucent mineral that exists in a diverse variety of colors. The color is changeable, the most common being green and purple; but fluorite may also be colorless, white, yellow, blue, or brown. Colors may result from the presence of impurity ions such as rare earths or Mn4+, hydrocarbon inclusions, or lattice defects. It is commonly found in crystalline cubes in veins and associated with lead, tin, and zinc ores. Fluorite is the most abundant fluorine-bearing mineral that occurs as cubes or compact masses and more rarely as octahedral with complex modifications. It is found in many localities around the world but only a few produce large quantities of high quality. Fluorite frequently emits a blue-to-green fluorescence under ultraviolet radiation, especially if rare-earth or hydrocarbon material is present. Also, some fluorites are thermoluminescent, that is, they emit light when heated.
Keywords: mineral, fluorescent, thermoluminescent
