         of different colors, such stones as the onyx and
         sardonyx, and various kinds of shells, being used. 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.
