Cameo

n. art of carving images on gems or other stones; gem or other stone which has been carved in this manner; short (often one-scene) appearance by a well-known actor in a film with lesser known actors, cameo role

For "brief appearance" see Cameo appearance. For other uses, see Cameo (disambiguation). Cameo is a method of carving, or an item of jewellery made in this manner. It features a raised (positive) relief image; contrast with intaglio, which has a negative image. The effect of "cameo" also refers to a proof coin that has frosted lettering and features, providing attractive contrast with the mirrored fields of the coin. The terms "deep cameo" and "ultra cameo" describe cameo coins having the boldest, most attractive contrast.

Noun
1. engraving or carving in low relief on a stone (as in a brooch or ring)
(hypernym) anaglyph

(n.)
A carving in relief, esp. one on a small scale used as a jewel for personal adornment, or like.
  

A style of carving in which the design motif is left and the surrounding surface is cut away leaving the design in relief. Cameos in jewelry are often made of shell, although hard stone cameos such as sardonyx are more valuable. Cameos have been carved from ancient times, and ancient motifs such as the goddess Athena or a Baccante or follower of Bacchus were popular cameo subjects in Victorian times, through the 1930's. Cameos are still being made today in Italy. A cameo habille is one in which "jewelry" such as a miniature diamond pendant is actually attached to the carving.
