Abstract
A jewelry closure includes a pair of magnetic closure members for magnetically engaging together and a mechanical closure which acts as a second closure or safety feature. One or both closure members includes a magnet. A first closure member of the pair is supported by a casing which extends outwardly to receive the second closure member for magnetic engagement of the members. A mechanical closure acts as a safety feature preventing the two members from being readily separated. The mechanical closure may include screw threaded portions on both the casing and the second closure member or may include a push-click mechanism on the casing and second closure member.
