Fluorite is a colorful mineral composed of calcium fluoride (CaF₂). It is known for its wide range of vibrant colors, including purple, green, yellow, and blue. Fluorite is commonly found in hydrothermal veins and is often associated with other minerals such as quartz and calcite. It has a cubic crystal structure and is used in various applications, including the production of aluminum and as a flux in steelmaking. In addition to its industrial uses, fluorite is popular among collectors and is often cut into gemstones. The mineral exhibits fluorescence, meaning it can glow under ultraviolet light, which adds to its appeal. Fluorite is also believed to have metaphysical properties, making it a sought-after stone in crystal healing practices.
