Abstract: An interchangeable jewelry assembly is provided which includes at least one jewelry element having a first side and a second side that is adapted for attaching to other jewelry elements or to jewelry support devices. A post is pivotally mounted on the second side such that it has at least two predetermined positions, an extended position for insertion into a pierced body part or fabric, and a retracted position whereby the post is substantially parallel and adjacent to the second side. A catch device also is located on the second side for fastening the free end of the post to the second side when the post is in its retracted position. When the post is fastened to the catch device, a loop is formed which may be used to attach the jewelry element to other jewelry support devices.
