Fluorite is a vibrant mineral known for its stunning range of colors, including purple, green, yellow, and blue, often displaying a striking banded appearance. This calcium fluoride mineral typically forms in hydrothermal veins, where hot, mineral-rich water cools and deposits the fluoride in cubic crystals, often alongside other minerals such as quartz and barite. Its remarkable fluorescence under ultraviolet light, which gives it its name, makes it a favorite among collectors and mineral enthusiasts. Additionally, fluorite is valued in the metaphysical community for its purported ability to enhance mental clarity and decision-making.
