This collection contains 15 long and short wave fluorescent mineral specimens. Fluorescence is an unusual property in that some minerals will emit visible light when exposed to short or long (black-light) wave ultraviolet light or x-rays. UV photon energy excites the electrons of these minerals and they move to a higher energy orbital (excited state). When the electrons fall back to the ground state they release that energy as visible light. Fluorescence is a reliable tool for mineral identification.
