Only 15% of all mineral species fluoresce, and not every specimen that can fluoresce does so. What gemstones show fluorescence under UV light? Banana spots, olive oil, certain flowers, and scorpions all fluoresce under UV light as well. What would happen if you put rocks or gemstones under a blacklight? Would they fluoresce?
