Puzzle ring
From Wikipedia, the free encyclopedia
A traditional puzzle ring is a type of finger ring made up of four, six, eight, or twelve interconnected rings. Contemporary designs include rings of five or seven bands. Reassembly is a form of mechanical puzzle. Many are Italian or English from the Renaissance period, although they are becoming more common in North America.
They were developed from gimmal rings, which derive their name from the Latin gemelli, meaning "twins." Gimmal rings were mainly used as wedding rings, because the wearer could not cheat on their spouse without taking it off first and then putting it back together afterward.
They are also sometimes called Turkish Wedding Rings or Harem Rings.
