Fluorite: CaF2. Named in 1797 by Carlo Antonio Galeani Napione from the Latin, fluere = “to flow” (for its use as a flux). The term fluorescence is derived from fluorite, which will often markedly exhibit this effect. The element fluorine also derives its name from fluorite, a major source for the element.
