Name:
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 of 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.

Crystallography of Fluorite
Crystal System:
Isometric
Class (H-M):
m3m (4/m 3 2/m) - Hexoctahedral
Space Group:
Fm3m
Cell Parameters:
a = 5.4626 Å
Unit Cell V:
163.00 ų (Calculated from Unit Cell)
Z:
4
Morphology:
Usually cubes, {001}; less often octahedrons, {111}; rarely dodecahedrons{011}. Also some hexoctahedrons and tetrahexahedrons. Combinations of these forms common, cube corners and edges are often modified. {001} usually smooth and lustrous, {111} rough and dull. Crystals distorted at times by unequal development of faces, as of {013}. Often markedly composite; minute cubes aggregated to form an octahedron at times or as an overgrowth of crystals upon the corners of an earlier formed crystal of differing habit. Massive; compact; earthy, columnar (rare), or in globular aggregates; botryoidal (rare).
Twinning:
On {111}, usually as interpenetrating cubes (e.g., Strzegom, Poland), but also as contact spinel twins (e.g. Naica, Mexico and Chumar Bakhoor, Pakistan).

Varieties of Fluorite
| Blue John | A banded white/purple variety of fluorite applied by locals in England. Originally described from Castleton, Derbyshire, England, UK. |
| Cerfluorite | A Ce-bearing fluorite. Known as a synthetic phase. |
| Chlorophane | A variety of Fluorite that exhibits green thermoluminescence. Originally described from Siberia, Russia. |
| False Amethyst | An old name for cut purple Fluorite. [Chester, 1896, 92 - "Dict.Names Min."] |
| Ratovkite | Fine-disperse variety of fluorite of sedimentary origin and with deep-violet radiation colour. First described from the Moscow area at the beginning of the 20th century. |
| Stink-Fluss | A variety of fluorite, especially from Wölsendorf, Germany, that emits an odor of HF and ozone upon grinding due to the internal presence of free fluorine and calcium and the interaction of components with water upon grinding. |
| Strontian Fluorite | Fluorite containing 2-18 mass.% of Sr. |
| Tiffany stone | A fine-grained purple to pale violet fluorite, usually with swirl patterns sometimes with small impurities of intergrown bertrandite, chalcedony, opal, and/or quartz. |
| Yttrocerite | Y-rich fluorite (see also yttrofluorite). Note: A great many occurrences of yttrocerite reported in the nineteenth century were false. The so-called "yttrocerite" has repeatedly been shown to be ordinary purple fluorite without enrichment of rare earth el... |
| Yttrofluorite | Yttrofluorite is a variety of fluorite containing an appreciable amount of trivalent yttrium (Y) taking the place of divalent calcium (Ca) cations in the fluorite structure. Many early identifications of yttrofluorite are likely to be purple fluorite with... |
