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.

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.
