(From Wikipedia, the free Encyclopedia)
Fluorite (also called fluor-spar or Blue John) is a mineral composed of calcium fluoride, CaF2. It is an isometric mineral with a cubic habit, though octohedrons and dodecahedrons are not uncommon.
Fluorite may occur as a vein deposit, especially with metallic minerals, where it often forms a part of the gangue (the worthless `host-rock' in which valuable minerals occur) and may be associated with barite, quartz and calcite. It is a common mineral in deposits of pneumatolytic origin and has been noted as a primary mineral in granites and other igneous rocks.

Blue John
One of the most famous of the older localities of fluorite is Derbyshire, England, where under the name of Derbyshire Blue John beautiful blue fluorite is used for ornamental purposes; its softness, however, has been a bar to general use.*Note on colours: The blue kind is often a delicate violet-blue, sometimes amethystine in tint. Certain specimens appear blue by reflected light and green or yellow by transmitted light. Fluorite sometimes phosphoresces when heated or scratched. Other varieties fluoresce beautifully under the influence of X-rays or ultraviolet light.
Crystallographic system Cubic Colours White or colorless, blue, blue-green, yellow, brownish-yellow, or red.* Lustre Vitreous Hardness 4 Refractive index 1.433-1.435 Specific gravity 3.18 Cleavage 1 (octahedral) Pleochroism None See also: List of minerals
