It fluoresces under ultraviolet light and in the presence of magic and strengthens other stones. ### Physical Description A common mineral composed of calcium and fluorine. Pure fluorite is colorless and transparent, but mineral inclusions color it many hues, with purple, pink, and green being most prevalent, with common banding and color zoning. Fluorite grows in cubic or octahedral crystals, interlocking to create sizable stones. It has four directions of perfect cleavage and when split, it often forms perfect eight-sided crystals. The gem often displays fluorescence, glowing with a blue-violet or cream light; the phenomenon was named after the mineral. When heated above 100 degrees Celsius, red and green fluorite become phosphorescent. Antozonite, known as "fetid fluorite," is an uranium-included radioactive variety, releasing a pungent fluorine stench when the rock is crushed. --- ## Occurrence Fluorite occurs as masses, veins, and crystals in rocks subjected to hydrothermal activity. It is common in sedimentary deposits, granites, pegmatites, and marbles. Often it is found accompanying quartz, calcite, and metallic ores, such as tin, silver, lead, zinc, and copper. ### Extraction & Preparation Fluorite is water-soluble and should never be left submerged in water for cleaning. Oil treatment improves luster, but it rarely influences the price of gems. --- ## Properties ### Decorative Properties An impressive range of colors makes fluorite an affordable and popular colored gemstone. However, the stones are easily scratched and suboptimal for jewelry pieces that come in contact with hard surfaces. Attractive color zoning makes fluorite a good material for small ornamental carvings. ### Industrial Properties Under the name of fluorspar, fluorite is the primary source of elemental fluorine and hydrofluoric acid, used in pharmaceuticals (including antidepressant medication), production of industrial materials, refining oil, and etching glass. It is employed as flux in steel manufacturing, to lower the melting point of raw materials. Polished fluorite pieces serve as lenses in microscopes and telescopes, as well as when observing far-ultraviolet and mid-infrared ranges, where conventional glass fails. ### Magical Properties Fluorite is a practical, yet often overlooked stone with multiple uses not only for magical practitioners. It glows in the presence of magic, making it useful for those willing to protect themselves from enchantments or magical traps. Antozonite may be crafted into traps triggered by the use of magic; the stone releases both the stinky, poisonous gas and radiation. Fluorite also strengthens the power of other stones. Thanks to its relatively low price and hardness, powdered fluorite is a common and easy to prepare "fairy dust," sprinkled atop other magical reagents to amplify their power. Used on its own, fluorite has a positive effect on the conscious mind, quelling disturbing emotions, encouraging focus and motivation, and finding one's path. It is a favorite of alchemists and researchers, as it enlivens the mind and calms the soul.
