Abstract: A structure bonding different metals for valuable ornaments includes a valuable ornament body which consists of at least a metal body and a hard metal element that are coupled together. The metal body and hard metal element have respectively a coupling surface with a latch flange and a latch trough formed thereon that are engageable with each other. Thus the metal body and the hard metal element can be bonded together securely. The valuable ornament body thus formed has a greater hardness. The bonding of different metals also provides a novel design different from the conventional ornaments.
