Scope note:

Small reliefs made from materials having layers of different colors, such as gems, glass, ceramics, or shell, and carved so that the design stands out in one color against a background in another. Cameos may be incorporated in jewelry. For works created from different pieces of stone and other materials, prefer "commessi (visual works)."
