Tiny, glowing, and impossible to ignore. Our sterling silver donut pendants are approximately 8mm in diameter and feature genuine Super-LumiNova® material that glows in the dark after exposure to light. The luminous center is baked and protected with a crystal-clear ceramic coating for lasting beauty. Finished on an elegant 18-inch sterling silver cable chain, this whimsical necklace is the perfect gift for donut lovers, night owls, and anyone who enjoys jewelry with a little extra glow.
