It belongs to the family of halide minerals, has a cubic appearance and is in isometric crystal system. Sometimes it can be a colorless crystal, but other times it can also be purple, blue, green, yellow, or pink, or other combinations of these colors. Named in 1797 by Carlo Antonio Galeani Napione from the Latin, fluere = "to flow" (for its use as a flux.) In 1852, George Gabriel Stokes discovered the ability of specimens of fluorite to produce a blue glow when illuminated with light, which in his words was "beyond the violet end of the spectrum." He called this phenomenon "fluorescence" after the mineral fluorite. Fluorescence in fluorite is thought to be caused when trace amounts of yttrium, europium, samarium, or other elements substitute for calcium in the fluorite mineral structure. I
