  • Publication number: 20160324279
    Abstract: An interchangeable jewelry system for creating custom jewelry assemblies, wherein at least three holes are punctured through the side walls of a pendant of any desired decorative appearance so that a cord may be threaded through the body of the pendent to create variable design patterns. The cord's length can be shortened by, for example, halving it through one of the holes in the pendant, which gives the jewelry system additional wearable utility as a necklace, wristlet, or ankle bracelet.
