Over 500 minerals have been discovered that exhibit some sort of fluorescence when exposed to ultra violet light, including fluorite, calcite, aragonite, corundum (rubies and sapphires!) cerrusite, hyalite opal, smithsonite, sodalite (like your Lake Superior Emberlites aka you-per-lights) and so many more!
