It crystallizes in isometric cubic habit, although octahedral and more complex isometric forms are not uncommon. Mohs scale of mineral hardness, based on scratch Hardness comparison, defines value 4 as Fluorite.
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. Fluorite Group. Fluorite is found as a common gangue mineral in hydrothermal veins, especially those containing lead and zinc minerals.It is also found in some greisens, granites, pegmatites and high-temperature veins, and as a component of some marbles and other metamorphic rocks.he term fluorescence is derived from fluorite, which will often markedly exhibit this effect.
