A synthetic resin article includes a translucent or semitranslucent external portion (10) and an internal portion (1) having on its external surface an ornament, in particular a gold or silver metallization. The external and internal portions (10 and 1) comprise complementary assembly structure (8, 14; 5, 11) and are assembled by wedging and ultrasonic welding. The internal portion (1) is formed of a thermoplastic resin selected from the group consisting of polyolefin, polyamide, PVC, polyethylene terephthalate and methylpentene resins. The external portion (10) is constituted of a translucent or semitranslucent synthetic resin. The internal portion (1) is a tubular element comprising a bottom (2) of larger transverse cross section than a tubular portion (3) of the internal portion (1) and which has a bent-back edge (4) extending along the tubular portion (3) of the tubular element creating a recess (5). The tubular element has at its open end opposite this bottom (2) a projection (8) on its external surface and the external portion (10) is a tubular element of dimensions corresponding to those of the internal portion (1), of which one of the ends has a projection (11) from its internal surface disposed in the recess (5) of the internal portion (1) and whose other end has an edge (15) bent back toward the interior of the tubular element creating a recess (14) in which is disposed the projection (8) of the internal portion (1).
