Thermoregulatory Interactive Gold Alloys for Therapeutic Jewelry Items

Abstract

Gold alloys are provided that offer therapeutic benefits to a biological organism by enhancing thermoregulation, metabolism, and improving blood circulation. In addition to the therapeutic benefits, the alloys retain their metallurgical properties, thereby allowing the alloys to be utilized with conventional lost-wax casting techniques as both jewelry items and therapeutic instruments. The alloys contain 88% to 95% gold, 2% to 10% platinum, 0.1% to 0.9% silver, 0.01% to 1.5% rhodium, and 0.01% to 1.5% iron.

I claim: 
     
         1 . A gold jewelry alloy comprising:
 88% to 95% by weight gold;   7% to 9.5% by weight platinum;   0.1% to 0.9% by weight silver;   0.01% to 1.5% by weight rhodium; and   0.01% to 1.5% by weight iron.   
     
     
         2 . The alloy of  claim 1 , wherein said alloy comprises:
 88% to 92% by weight gold;   7% to 9.5% by weight platinum;   0.4% to 0.9% by weight silver;   0.01% to 0.9% by weight rhodium; and   0.01% to 0.9% by weight iron.   
     
     
         3 . The alloy of  claim 1 , wherein said alloy comprises:
 88% to 95% by weight gold;   3% to 10% by weight platinum;   0.1% to 0.9% by weight silver;   0.01% to 1.5% by weight rhodium; and   0.02% to 1.5% by weight iron.
