A round black carved onyx cameo is bezel set in 18K yellow gold in this pendant accented with a small faceted ruby beneath the cabled bail! While the bail is not hinged, it has a 5-millimeter opening to fit a larger chain, cord, ribbon, or even a narrow-gauge chain link bracelet. In very good condition, it has marks on the metal. How you use this versatile piece is only limited by your imagination!
