The classical cameos made in Italy are carved on a seashell (see cameo conch, below), having an olive figure carved from the inner layer of the shell in relief on the white background of the outer layer of the shell.
Cameo conch Zool., a large, marine, univalve shell, esp. Cassis cameo, Cassis rua, and allied species, used for cutting cameos. See Quern conch.
