The invention relates to a process for the production of a part provided with an external element comprising the following steps:

    provide an electrically conductive substrate having an upper surface and a pattern forming a recess in said upper surfacedeposit an electrically insulating layer into the pattern so that the insulating layer extends as far as the upper surfacedeposit a metal layer onto the upper surface of the substrate by galvanic growth so that at the end of this step the metal layer partly rests on the insulating layerdissolve the insulating layercover an assembly comprising the substrate and the metal layer with a mass of a base material of the part, wherein the mass forms an imprint of the assemblyseparate the mass and the metal layer from the substrate, wherein the mass then exhibits an external element with a shape corresponding to the imprint of the pattern.
