Fluorescent halite specimens from the Bohnia mine in Poland are truly stunning examples of the beauty that can be found in minerals. When viewed under ultraviolet (UV) light, these specimens emit a vibrant, orange color that is truly mesmerizing. Halite, also known as rock salt, is a mineral composed primarily of sodium chloride (NaCl). It is typically colorless or white, and is commonly found in sedimentary rocks and salt domes. However, when exposed to UV light, certain impurities within the halite can cause it to fluoresce. In the case of halite specimens from the Bohnia mine in Poland, the fluorescence is caused by the presence of trace amounts of manganese (Mn) and/or lead (Pb) within the crystal lattice of the halite. These impurities absorb UV light and then emit the blue color that is visible to the human eye. The fluorescence of these halite specimens is particularly striking due to the contrast between the bright blue color and the white or colorless background of the mineral. When viewed under UV light, the halite crystals appear to glow from within, creating a beautiful and ethereal effect. Overall, fluorescent halite specimens from the Bohnia mine in Poland are a must-see for any mineral enthusiast or collector. Their unique and mesmerizing beauty is truly a wonder to behold. condition as on pictures. Color is very difficult to reproduce in the pictures. Some pictured specimens show slightly different shades that seen with a human eye.
