The puzzle ring was a series of golden bands that could be manipulated into one ring. A puzzle ring created by the dwarves was given by Orik to Eragon on their journey to Ellesméra. The elf Nari solved the puzzle ring in moments, though Eragon couldn't solve it until after the Blood-Oath Celebration, once he had been changed into an elf-human hybrid. Even though Nari solved the puzzle quickly, he recognized its cleverness.
Trivia
The puzzle ring is based on one that a librarian gave to Christopher Paolini during a book tour for the self published edition of Eragon.
