The amulet has a metallic golden color. It depicts the head of a humanoid being with horns and tribal adornment. The amulet is worn using a black cord that easily goes over the head and into the neck of the wearer.
Castiel, who was searching for God, turned up and informed Dean that the amulet that he wore was an indicator that could lead them to God; according to him, the head piece would burn hot in the presence of God. Dean handed him the amulet, albeit reluctantly, noting that he felt "naked" without it.
After the brothers returned from Heaven, Castiel came back to return the necklace, stating that it was "worthless". Dean, possibly disillusioned by how all of Sam's "happy memories" were ones away from him, dumped the amulet into a wastebasket on his way out of the motel.
- Since the amulet was disposed in Dark Side of the Moon, many fans clamoured for its return. Some speculated that the amulet may resurface later on when the brothers' relationship returned to how it was before the Apocalypse. However, it has never been confirmed by any of the writers, cast or crew.
- When interviewed at Paleyfest '11, Eric Kripke has stated: "There are no plans to return the amulet," before jocularly adding, "It's doing a guest shot on One Tree Hill," referring to its diva-like nature.
- The amulet is visible during the flashbacks of Repo Man, Bad Boys, and Reichenbach.
- Although there are many replicas of the amulet, many of them, including the official WB one, are highly innacurate. THIS ONE is the most accurate.
