Structure bonding different metals for valuable ornaments

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.

1 . A structure bonding different metals for valuable ornaments comprising a valuable ornament body which includes at least a metal body and at least a hard metal element that are coupled together, the metal body being a metal of a greater value and having a first coupling surface which has a latch flange formed thereon, the hard metal element being a metal of a greater hardness and having a second coupling surface which has a latch trough formed thereon, the latch trough having a narrower front side and a wider rear side, the first coupling surface and the second coupling surface being corresponding and engageable with each other, the latch flange being wedged and filled in the latch trough to form a secured coupling. 
   
   
       2 . The structure of  claim 1 , wherein the valuable ornament body is selectively a ring, a necklace, a pendant or an earring. 
   
   
       3 . The structure of  claim 1 , wherein the metal body is selectively gold, Karat gold, platinum or silver. 
   
   
       4 . The structure of  claim 1 , wherein the hard metal element is selectively a titanium alloy, stainless steel, tungsten steel or an aluminum alloy.
