Puzzle ring

From Freepedia

A Puzzle ring consists of four, six, or eight interconnected rings that, when correctly aligned, can be an impressive finger ring. When apart, it's difficult to believe they can be manipulated to form an interconnected whole. Re-assembly is very difficult. They were developed from gimmal rings, which derive their name from the Latin gemelli, meaning "twins." Gimmal rings were mainly used as wedding rings. Many are Italian or English from the Renaissance period.

Today, puzzle rings are very common in Turkey, but most are not very well made and are often from cheap alloy rather than gold, silver, or platinum. Some rings can incorporate a set stone. Others use a mixture of the precious metals for the different bands.
