Fluorite is a colorful and widely collected mineral known for its vibrant fluorescence under ultraviolet light and wide color range. This particular example is a vivid yellow fluorite weighing 13.68 carats, notable for its bright and eye-catching coloration. Fluorite crystals form in hydrothermal veins and sedimentary environments, frequently crystallizing in well-formed cubic shapes. It is softer than many gemstones, with a Mohs hardness of 4, making it more suitable for collections and display rather than everyday jewelry. Fluorite is prized among mineral collectors for its clarity and range of colors, including green, purple, blue, and yellow. The Antwerp Laboratory for Gemstone Testing (ALGT) is a specialized institution that grades and identifies such minerals. Apart from its aesthetic appeal, fluorite has industrial uses as a flux in steelmaking and in the manufacture of certain glasses and enamels.
