OverviewFluorescenceHistory and etymologyStructureOccurrence and miningColorUsesImages

George Gabriel Stokes named the phenomenon of fluorescence from fluorite, in 1852. Many samples of fluorite exhibit fluorescence under ultraviolet light, a property that takes its name from fluorite. Many minerals, as well as other substances, fluoresce. Fluorescence involves the elevation of electron energy levels by quanta of ultraviolet light, followed by the progressive falling back of the electrons into their previous energy state, releasing quanta of visible light in the process. In fluorite, the

FLUORITE – Mardani Fine Minerals

In fine examples of zoned fluorite from Illinois, the colors are vibrant, and the distinctions between them sharp. This specimen exhibits exceptionally vivid color and exceptional luster. Yellow is among the rarer colors of the Illinois fluorites, and even when found, yellow specimens tend to be corroded and lusterless. This example is a brilliant, richly saturated, golden yellow with an ...

The refractive indices of all glasses at present available lie between 1.46 and 1 90, whereas transparent minerals are known having refractive indices lying considerably outside these limits; at least one of these, fluorite (calcium fluoride), is actually used by opticians in the construction of certain lenses, so that probably progress is to be looked for in a considerable widening of the ...

Fluorite with Quartz - Crystal Classics Fine Minerals

Perhaps the most iconic alpine mineral is pink Fluorite, a colour very rarely found around the world. This gorgeous example is from Zinggenstöcke in the Grimsel area, about 75 km SE of Bern in Switzerland. The Fluorite forms three octahedral crystals, two of which are intergrown. The largest measures approximately 2.5 x 2.5 x 2.0 cm and all are of a slightly burnt candy-pink, translucent and ...

Calcium fluoride - Wikipedia

Calcium fluoride is the inorganic compound of the elements calcium and fluorine with the formula CaF 2. It is a white insoluble solid. It occurs as the mineral It is a white insoluble solid. It occurs as the mineral fluorite (also called fluorspar), which is often deeply coloured owing to impurities.

The Differences Between Fluorite Calcite Sciencing

Fluorite and calcite, two mineral types, are vastly different in shape and behavior. For example, fluorite grows using a symmetrical crystal system, while calcite forms asymmetrically. Calcite is considered a common mineral, while fluorite is a semiprecious mineral. The two are found in vastly different environments and locations throughout the ...

Fluorite comes in a wide range of colors and has consequently been dubbed "The most colorful mineral in the world". Every color of the rainbow in various shades are represented by fluorite samples, along with white, black, and clear crystals. Pure Fluorite is colorless; the color variations are caused by various various impurities.

Pros and Cons of Fluorite as a Gemstone Free Essay

For example, the fact that fluorite reaches only 4 points in Mohs scale shows that the mineral is far too fragile compared to emerald, diamond and other gemstones. If fluoride were harder, it would be a perfect for replacing gems in jewelry. However, a relatively low hardness rate does not allow fluorite to become an impeccable substitute for precious gems in jewelry
