48 The modular system according to the present invention allows to modify the colour and the external finishing of wedding rings or generally rings and other articles of jewellery and cheap jewelry, by the covering of a central module (1) with a plurality of superposed blades (2, 3) and/or with the subsequent addition, by means of connecting systems like pressure connection, release insertion, screwing, joint connection, of a plurality of modelled and coloured anular structures (36). The industrial process for the realization of the modular system provides the shaping of tubular structures (63-64-65) with a plurality of coaxial layers, of different metals, with subsequent cutting and finishing, or the succession of electroplating deposits or subsequent casting.
