  • Patent number: 5253490
    Abstract: A hinged insert ring which comprises two precisely crafted ring bodies which are joined together at the bottom of their shanks, which each have two protrusions, with pins thereby creating an operable hinge. The ring bodies are each made of any base metal (e.g. gold, silver, platinum, brass, copper, etc.), and can be formed into any aestetically pleasing design or shape. The hinged double ring can open or close to provide entirely different looks. When the the two precisely crafted ring bodies are in an "open position", a third, independent ring body, with a different design or having a stone or other piece of jewelry attached at its top, can be inserted therebetween and enclosed within the first two ring bodies when they are place in the "closed" position by way of the hinge means. In the closed position, on the other hand, the two precisely crafted ring bodies form a completed ring. This new and unobvious design allows for the wearer to own a single ring yet have an entire line of different looking pieces.
