This pendant, bearing a glow of mystic-seeming power, can be worn by costumers and LARP players alike. It holds an acrylic crystal and integrated LED firmly in a solid ABS frame. Each can be cast and/or painted in a range of colors. The LED light is powered by a single CR1632 power cell held firmly in its battery clasp, inserted positive (flat) side out to turn on the light.
