Cerberus: In Greek mythology, this ferocious three-headed hound of Hades guards the entrance to the Underworld, keeping the dead from escaping and the living from entering. This Cerberus Necklace from our Creatures of Night Collection features a handmade bronze Cerberus pendant on an 18-inch 14k gold-filled paperclip style chain. A sterling silver version of this necklace is coming soon. Each Cerberus Necklace comes on a decorative card back telling the story of Cerberus.
