This process is characterised in that, starting with a pre-model (template), two identical metal blanks are produced, the second blank is hollowed out, a first rubber mould is manufactured from the first blank and, using the second blank, the so-called "lost-wax" process is implemented in order to obtain an article element in the first metal, the article element is positioned in the first mould and, using the latter thus fitted, the so-called "lost-wax" process is repeated in order to manufacture the final jewellery article 5.
