Laser Fluorescence in Calcite: this unique natural calcite specimen demonstrates strong fluorescence not only under UV but under longer wavelengths too. A high intensity 532nm green laser produces bright orange, a 445nm blue laser produces yellow light, and a near UV 405nm laser creates a pale whitish glow. The colorful glows comes from complex quantum mechanical behavior where photons are absorbed by trace amounts of Mn²⁺ (manganese in 2 ionic state) that take the place of calcium in the CaCO₃

These gorgeous Rainbow Optical Calcite spheres give off sooo much light and sparkle! We’ll have a variety of calcite colors to choose from ❤️ Did you know that the rainbows that you see are actually optical illusions caused by the way light bounces off the internal inclusions and cleavage of the calcite? Grab yourself a piece of the rainbow during our “Shimmer & Sparkle” live on Friday 12/12 @ 3PM CST ⏰ #opticalcalcite #opticalcalcitesphere #calcite #rainbowcalcite #crystals #crystalshop #thesto
