Procedure to obtain the diamond effect on a precious metal chain with hollow links, that comprises the following phases: Advance step by step of a semi-manufactured product chain made of hollow links, by means of a cold molding station; At each stop, in the molding station, carrying out in logical correspondence the descent towards a matched mold, of at least one core and at least one mold, in which said core can be moved perpendicularly through the mold, placed inside each individual link of the corresponding segment of chain, disposing the perimeter surface in contact with the interior perimeter of each link; Descent of the mold with simultaneous deformation and disposition of each link; For this reason, partial ascension of the core, with the mold and matched mold remaining in closed position; Ending of the ascension of the core until extraction of the corresponding link, with ascension towards the top part of the mold for a successive cycle that must be carried out on the segment of successive links.
