Method for Producing Layered Rings

Abstract

A ring formed of a first gold layer and second silver layer wherein the silver layer is more than fifty percent of the ring weight. The layers are bonded together with the gold layer on a portion of the outer surface to give an appearance of a ring formed entirely of gold. A method for fabricating the ring is also provided.

1 . A layered jewelry ring comprising:
 a. a first layer that encompasses a portion of the circumference on the outer surface of said ring;   b. a second layer that encompasses substantially all of the circumference on the inner surface of said ring;   c. a solder containing interface between said first layer and said second layer;   whereby said first and second layer are bonded together to form a single fused assembly shaped into a ring.   
   
   
       2 . The ring of  claim 1  wherein said first layer and said second layer are formed of the same material. 
   
   
       3 . The ring of  claim 1  wherein said first layer and said second layer are formed of different materials. 
   
   
       4 . The ring of  claim 1  wherein said first layer is formed of a metal, alloy, or combinations thereof. 
   
   
       5 . The ring of  claim 1  wherein said first layer is formed of gold. 
   
   
       6 . The ring of  claim 1  wherein said second layer is formed of a metal, alloy, or combinations thereof. 
   
   
       7 . The ring of  claim 1  wherein said second layer is formed of silver. 
   
   
       8 . The ring of  claim 1  wherein said first layer is about 0.05 to 0.50 cm thick. 
   
   
       9 . The ring of  claim 1  wherein said second layer is about 0.65 to 0.75 cm thick. 
   
   
       10 . The ring of  claim 1  wherein said second layer comprises more than fifty percent the weight of said ring. 
   
   
       11 . A layered ring comprising:
 a. a first layer formed of gold or gold alloy, said first layer encompasses a portion of the outer circumference of said ring;   b. a second layer formed of silver or silver alloy, said second layer encompasses substantially all of the inner circumference of said ring;   c. a solder containing interface between said first layer and said second layer;
 whereby said first and second layer are bonded together to form a single fused assembly shaped into a ring; 
 said ring formed such that said first layer is the primary visible layer when said ring is worn. 
   
   
   
       12 . A method for manufacturing a ring of  claim 1  comprising the steps of:
 (a) laminating a first plate to a desired thickness forming a first laminated plate;   (b) laminating a second plate to a desired thickness forming a second laminated plate;   (c) cutting a first blank from said first laminated plate;   (d) cutting a second blank from said second laminated plate;   (e) stamping a shelf on said second blank forming a stamped shelf;   (f) soldering said first blank onto said second blank in an area defined by said stamped shelf, said soldered blanks collectively forming a soldered assembly;   (g) passing said soldered assembly through an oven;   (h) stamping said soldered assembly in a press and forming a bonded assembly with a fused edge;   (i) cutting excess edge from said fused edge;   (j) stamping a form onto said bonded assembly;   (k) shaping said bonded assembly into a curved ring shape having two opposing ends;   (l) cutting a joint on the ends of said curved bonded assembly;   (m) soldering each of said ends one to another and forming a ring; and   (n) polishing said ring.   
   
   
       13 . The method of  claim 12  further comprising finishing said ring with desired designs, stone, stones, or combinations thereof.
