Cameo- a method of carving, or an item of jewelery or vessel made in this manner. It features a raised (positive) relief image; contrast with intaglio, which has a negative image. There are three main materials which are used for cameo carving: shell, agate (this is called a hardstone cameo), and glass.
Cameos can be produced by setting a carved relief, such as a portrait, onto a background of a contrasting colour. This is called an assembled cameo. Alternately, a cameo can be carved directly out of a material with integral layers or banding, such as (banded) agate or layered glass, where different layers have different colours.
Sometimes dyes are used to enhance these colours.
