Form Color What is Fluorite?

These properties are caused by impurities or structural defects in fluorite. These color forming impurities are of two types- they either substitute calcium or fluorine atoms in the structure or are present as microscopic inclusions that shift the color by filtering and/or scattering light. Fluorite is colored by a variety of extremely complicated mechanisms. The most common color causing ...

Why Fluorite Comes in Different Colors? With Examples

Pure Fluorite is colorless; the color variations are caused by various various impurities. The most common colors are purple, blue, green, yellow, or colorless. Less common are pink, red, white, brown, and black. Color zoning or banding is commonly present. The color of the fluorite is determined by factors including impurities, exposure to radiation, and the absence or voids of the color ...

Barite Inclusions in Fluorite - GIA

The upper portion of the inclusion was enclosed in a fluorite color layer that showed a strong purple-to-blue color change. The white inclusion served as an excellent background on which to display this dra-matic change of color. The Raman analysis revealed a spectral match for barite in each of the three inclusions (figure 4). All of the major peaks for barite were present in all of the ...

Why does fluorite have different colors? Geology Page

The many colors of fluorite are truly wonderful. The rich purple color is by far fluorite’s most famous and popular color. It easily competes with the beautiful purple of amethyst. Often specimens of fluorite and amethyst with similar shades of purple are used in mineral identification classes to illustrate the folly of using color as the sole means to identify minerals. The blue, green and ...

[Analysis of color regulation of Fluoritum in Chinese ...

The different colors of fluorite are mainly caused by the impurity elements. At present, there are mainly about the coloration mechanism of fluorite: rare earth ions (4fN ions), color center, inclusions, crystalline domains or sub microscopic inclusions. The green of fluorite is produced by 570 nm and 305 nm absorption peaks which are caused by Sm2+ and compensated ions Na+ centers generated ...
