Puzzle ring

A puzzle ring is a type of jewelry ring made up of four, six, eight, or twelve interconnected rings. Contemporary designs include rings of three, 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 likely developed from gimmal rings.

The puzzle ring is also sometimes known as the "Turkish wedding ring" or "harem ring." Per apocryphal legend, the ring would be given as a wedding ring, because if the wearer removed it to cheat on their spouse, they would be unable to reassemble the ring before its absence would be noticed.
