Fluorite

Fluorite is a colorful mineral composed of calcium and fluorine, often forming in cubic or octahedral shapes. It appears in various hues like purple, green, yellow, and blue, making it popular for decorative and collectible purposes. Fluorite has a relatively low melting point and is used in manufacturing certain types of glass and ceramics. Geologically, it forms in hydrothermal veins, often alongside metals like lead and zinc. Its vibrant colors and clarity also make it valuable in optics and as a source of fluoride for dental and industrial applications.
