In every Egyptian collection of importance a large number of rings, having a gap in each, will be found; they are made of gold, red jasper, obsidian, red glazed faïence, shell, stone, and glass. Those made of gold have a small ring at each end for a wire to pass through (?), and they may thus have been used as earrings or pendants for necklaces ; on the other hand they may have been used as amulets. Some believe that they were used as buttons.
