Warehouse 13, Palladium-Infused Crystalline Necklace

original movie prop

In the show's first season, we meet former Warehouse 13 agent James MacPherson, who turned rogue dealer in artifacts and was subsequently banned from the Warehouse forever, enforced by a permanent modification to his blood which would cause his near-instantaneous death by acid disintegration if he set foot inside the building.  In a twist of fate, MacPherson is eventually captured and imprisoned in the Bronze Sector of the Warehouse itself, with this necklace of palladium-infused diamonds placed on his neck to temporarily shield him from harm. Of course, he then manages to escape almost immediately, still wearing the stones.

Multiple irregular translucent rubber 'diamonds' on a leather cord.  The stones are made of a very soft crumbly rubber, with the hook and cord just pushed through the center of each one. Many of the stones have broken off; an included bag of  production-used crystals consists mostly of fragments that may have once been on the necklace. With a continuity photo of actor Roger Rees.
