Dean threw it away in a motel room in S5. God has it in S 11 and that has never been explained. Bur, as you said, he is God, after all. It burns in God's presence because that was what it was esigned to do. It's no dfferent than any other "magic item" in this series. That's what it was made to do.

And when God had Dean's necklace in S 11, he put it back in Sam's pocket after saving the town in "Don't Call Me Shurley."
