One Ring to Rule Them All

While this ring can fit over four wrists, it is worth noting that this was just used as a prop from the hit trilogy, Lord of the Rings. The movie is inspired by a novel written in 1937 by author J.R.R. Tolkien.

Also known as the Ruling Ring, this ring should be given credit for the success and popularity of the movie, The Lord of the Rings. It first appeared in The Hobbit as a magical ring that can allow the wearer invisibility. While it seemed to be simply made of gold, this ring is entirely resistant to damage. It can change its size, as well as its weight. It can also grow bigger if it wants to escape from its wearer.
