Abstract
A jewelry closure includes a magnetic closure and a mechanical closure which is a safety feature, preventing the magnetic closure from being opened inadvertently. A plate-like mechanical closure member attached to one of the magnetic closure members engages a complementarily shaped portion of the other magnetic closure member when the magnetic closure is secured to provide a mechanical second closure for the jewelry. The combined magnetic and mechanical jewelry closure may be used to close chains. The closure may also be disposed on a hinged ring. The ring may be used for passing through ends of a decorative chain as a closure for the chain. The closure may also be used on a hinged ring for wearing on a finger and is particularly useful if the finger joints are swollen. Other uses include adaptation for a hinged charm for closing a chain or for adding to a chain.
