The Cameo comes from the shell of the shell which, already in the first phase of production, is processed by a craftsman who cuts the upper part, creating what the sector's operators call "The cup of the shell". The upper part is designed by another craftsman who, by demarcating the individual pieces with a black felt-tip pen, decides which of these must then be used for processing. The shells, well defined, are then given to an expert cutter who sharpens the pieces using a very sharp rotating instrument. At this point, each piece of the shell is carefully polished and polished by a rotating brush. The next step is to place each piece on a wooden stick, spreading a special glue at a certain temperature on both sides of the stick. In the last phase of production the artist can first draw and then engrave with a particular tool, better known as "Bulino", classical profiles, biblical or mythological scenes, reproducing sculptures of low relief in miniature, thus giving life to the Cameo.
