[TropesWiki] baf says, "I remember some discussion of the protective magic on the One Ring that prevented it from being destroyed, and it was pointed out that the main protection wasn't the whole 'can only be destroyed in the fires of Mount Doom' thing. It was the 'anyone who has this ring cannot bring themselves to destroy it'."
