The Gemstone Fluorite
Fluorite makes a beautiful gemstone that comes in all colors, and can often be multicolored with two or more contrasting color within the same gemstone. Multicolored Fluorite gemstones often show banding patterns. Large and flawless crystals are fairly common, and these can produce very large and totally clear gemstones. However, due to Fluorite's very low hardness and perfect cleavage, it cannot be used as a mainstream gemstone, and it is generally cut specifically for specialty collectors.

All About
Most Fluorite gemstones are from deeply colored stones, but they can also be cut from the less intense color forms. The most popular color for Fluorite is purple, and deep purple Fluorite can closely
resemble
Amethyst. Fluorite is often brightly
fluorescent in
ultraviolet light. In fact, the term
fluorescence is derived from Fluorite. Due to the very low
hardness and perfect
cleavage of Fluorite, special care must be taken to ensure it doesn't get scratched or chipped.
Uses
?
Fluorite is not commonly used as jewelry, and is cut mostly for collectors. Small varicolored beads of Fluorite are sometimes strung for use as a bracelet. Fairly large gemstones have been cut from Fluorite, and round cuts with concave patterns are typical.
Banded and multicolored Fluorites are sometimes cut and
polished as
cabochons. The
banded variety
Blue John was once used for ornamental carvings and as goblets.
