  • Patent number: 5239841
    Abstract: A spring wire or other spring-like material is formed with a circular ring portion which has a diameter adapted to fit snugly around a nipple of a human breast. The wire or material also forms two overlapping end portions which project outwardly from the ring portion and are compressed together to enlarge the ring portion so that it may be conveniently placed on the nipple and removed from the nipple. When the end portions are released, the ring portion grips the peripheral surface of the nipple. Preferably, the end portions comprise smaller circular rings which may be used to support different forms of jewelry, and the ring portion may also support a decorative element which covers the nipple. The ring portion and end portions are decorated, preferably by plating with a precious metal.
