  • Necklace and bracelet pendant-clasp
    Patent number: 6804977
    Abstract: The combination pendant clasp of this disclosure is suitable for a necklace or bracelet. It provides a positive locking clasp which is manipulated in front of the wearer. The pendant clasp has two principle members, both of which may be decorated with precious stones, and may symbolize a relationship between individuals. Placement of the clasp in the front of a necklace or bracelet avoids the chance that the clasp will become inadvertently and unnoticed open and the jewelry lost.
