ABSTRACT:
A gold based jewelry alloy is disclosed of preferably the 10 to 18 karat range containing primarily gold, copper, zinc and silver. This alloy is formulated to create a unique color, a mid-range hue with a fresh, soft appearance that is very complimenting to a variety of skin tones and gem stones. Aside from characteristics of appearance, the alloy disclosed has an increased hardness over standard yellow alloys for longer wear and improved polish holding characteristics. The alloy disclosed has excellent castability and formability and responds well to typical jewelry manufacturing processes (i.e., tooling, stone setting, soldering, remelting, forging and plating). The alloy contains about 40% to about 76% gold, about 20% to about 52% copper, about 0% to about 12% zinc and about 0% to about 12% silver.
