Fluorite is a highly sought-after calcium fluoride mineral prized for its exceptional clarity and vibrant rainbow of colors. This crystalline gemstone forms in cubic and octahedral shapes through hydrothermal processes, creating specimens that range from completely transparent to translucent with stunning internal patterns. Fluorite is particularly valued by collectors and jewelry enthusiasts for its perfect cubic cleavage and intense fluorescence under ultraviolet light.
