(57) A method of making a multicolor product (1, 11; 22) with longitudinal development
of precious material adapted to be used for manufacturing wearable ornamental articles
such as armlets, necklaces, and the like is disclosed comprising the following steps:
providing one or more coated wires (3) each consisting of a central element (4, 17)
of precious metallic material covered by one or more coaxial external twisted sheaths
(5,18; 19) also made of precious metallic materials having different colors from each
other and relative to the color of the material of the central element (4, 17); manufacturing
an unfinished product (7, 15, 21) with longitudinal development using at last one
of the coated wires (3) on which one or more mechanical workings are carried out;
