Abstract: A substrate includes a final silver-plated surface protected against silver tarnishing by a protective coat having a thickness between 1 nm and 200 nm, the protective coat includes a first coat of Al2O3 deposited on said final silver-plated surface and having a thickness between 0.5 nm and 100 nm, and on the first coat of Al2O3, a second coat of TiO2 having a thickness between 0.5 nm and 100 nm, the substrate including a coat of a silver and copper alloy comprising between 0.1% and 10% by weight of copper with respect to the total weight of the alloy, forming said final silver-plated surface, said coat of a silver and copper alloy having a thickness between 1000 nm and 3000 nm. Embodiments also relate to a method for manufacturing such a substrate.

Abstract: A method is described for protecting a silver surface against tarnishing. This involves depositing a layer of a silver-copper alloy on a substrate, which may be a silver substrate. The alloy comprises between 0.1 wt % and 10 wt % of copper relative to the total weight of the alloy. At least one layer of a metal oxide or a nitride having a thickness in a range of 1 nm to 200 nm is deposited on the alloy to protect against tarnishing. The presence of copper in the silver-copper alloy enhances the alloy's adhesion without altering the silver color.

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.

Abstract: A method for assembling a stone on to a mounting, the stone being cut to have a crown, a girdle and a pavilion, the method including providing a substrate including an adhesive layer; positioning the stone on the adhesive layer; heating the adhesive layer; exerting a pressure on the stone; positioning a setting sheet around the stone above the adhesive layer, so as to form a peripheral free space between the setting sheet and the stone, at least at the level of the girdle and of areas of the crown and the pavilion adjacent to the girdle; depositing a metallic layer in the peripheral free space from the setting sheet, at least at the level of the girdle and of the areas of the crown and the pavilion adjacent to the girdle, the metallic layer and the setting sheet forming the mounting; releasing the stone and its mounting from the substrate.

Abstract: A method for assembling a stone on to a mounting includes sinking the stone into an adhesive layer on a substrate and then positioning a setting sheet around the stone above the adhesive layer so as to form a peripheral free space between the setting sheet and the stone, at least at the level of the girdle and of areas of the crown and the pavilion adjacent to the girdle. Then, a metallic layer is deposited in the peripheral free space from the setting sheet, at least at the level of the girdle and of the areas of the crown and the pavilion adjacent to the girdle, such that the metallic layer and the setting sheet form the mounting.
