  • Patent number: 5577396
    Abstract: An earring convertible into a pendant accessory for a second earring. The earring has an anchor contained within, the anchor not protruding from the ornament of the earring, and having a threaded socket. For conventional use as a primary earring, a stud passes through the ear lobe and threads into socket. A clasp entraps the ear lobe between the ornament and the clasp in conventional manner. To convert to a pendant accessory, the stud is replaced by a second stud having an enlarged head. The enlarged head is drilled to have an opening larger than the stud of the second earring. The second stud encircles the stud of the primary earring, and threads into the socket of the ornament of the convertible earring. The ornament of the convertible earring now depends from the primary earring.
