Earth Treasures: Fluorite
By Chisom Ibemere
Fluorite is the mineral form of calcium fluoride. It belongs to the group of halide minerals. It has been used for decorative and ornamental purposes for ages. Its name is gotten from the Latin word “fluere,” which means “to flow.”
Fluorite was discovered first in the 16th century, and was used by peasants in Germany as a flux for smelting metals. Historically, the Chinese made use of fluorite in carvings and ornamental purposes.
Fluorite has been on existence for centuries and known worldwide for its numerous uses. It is used in the manufacture of optical equipment, chemical industries, and as a decorative ornamental stone. It has unique colors and patterns which makes it a popular addition to gemstone collections. It is also used for faceting, cabochon carving, and other forms of lapidary arts. Fluorite may also be used in alternative healing practices.
Fluorite is a halide mineral. It has a cubic or octahedral crystal structure. It can be found in a wide range of colours such as purple, green, blue, yellow, and pink. Fluorite has a hardness of four on the Mohs scale, which means it is softer than some gemstones. It exhibit fluorescence, when exposed to ultraviolet light.
Fluorite occurs in many locations like the United States, Canada, Mexico, China, and Russia. It also occurs in hydrothermal vein deposits, where it is formed by hot water circulating through rocks and minerals. Fluorite can also be found in sedimentary rocks, and is sometimes mined as a byproduct of other minerals such as lead, zinc, or copper.
The value of fluorite depends on its size, quality, colour, and transparency. Large, high-quality fluorite samples have high price and highly sought.
