Abstract: 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 surface deposit an electrically insulating layer into the pattern so that the insulating layer extends as far as the upper surface deposit 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 layer dissolve the insulating layer cover 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 assembly separate 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.

Abstract: The invention relates to a method for mounting at least one decorative element (3) on a support (2) comprising the steps of: a. taking a support (2) provided with at least one cavity (4); b. taking at least one decorative element (3); c. filling said cavity with a composite filler material comprising at least one metal powder and at least one organic binder and having, at the moment of filling, a viscosity comprised between 1,000 mPa·s and 1,000,000 mPa·s; d. heating the composite filler material to a higher temperature than its melting point to make it liquid; e. allowing the filler material to cool to form a substrate (6); f. making at least one housing (8) in said substrate (6); g. mounting said decorative element (3) in said housing (8). The present invention also concerns a decorative support (2) provided with at least one cavity (4) filled with said filler material forming a substrate (6) in which at least one housing (8) is formed, said housing (8) being arranged to receive said decorative element (3).

Abstract: A method of decorating an element. This method includes the following steps: taking the element (1, 11, 21, 31), the element including anchoring for improving the securing of the decoration (5) to the element; making a mask (4) of the desired thickness of the decorations (5), and having at least one opening (4′); placing the at least one opening in the mask (4) against the place to be decorated so as to form at least one mould (4′, 6, 6′, 6″,100); filling the at least one mould with an at least partially amorphous material via hot forming; and removing the mask (4).

Abstract: A method for assembling a stone on a setting support, the stone being cut to exhibit a table, a crown, a girdle and a pavilion. A substrate with a recess for the stone, the recess forming, between the substrate and the stone, a peripheral free space in the vicinity of the girdle and of the zones of the crown and of the pavilion contiguous to the girdle, the peripheral free space including a bottom having a conductive surface. Electroplating, in the peripheral free space, a metal layer in the vicinity of the girdle and of the zones of the crown and of the pavilion contiguous to the girdle, so as to confine the girdle in the metal layer to form, around the girdle, the setting support. The stone and its setting support are released from the substrate.
