KARATIUM WHITE

A jewelry alloy that is approximately a 10% or 2.4 karat alloy that has similar color huge and shine and characteristics of 10 karat white gold and higher. This alloy is considerably less expensive than traditional 10 karat white gold and higher, but has all the similar working characteristics as working in sterling or 10 karat white gold metal alloys. The alloy has the following compositions by weight; Gold 5.00-20.00%, Silver 75.00-92.50%, Copper 01.00-10.00%. In addition to its nice white (silver) color and low cost it provides retailers with an affordable alloy for jewelry and provides jewelry craftsmen a low cost white (silver) alloy that responds well to the jewelry manufacturing process (e.g., casting, milling, soldering, tooling, stone setting, polishing and plating).

Description
Background of Invention

Even before the recent increase in the price of precious metals in this estranged economy I found an artistic purpose to develop new colored alloys that would be wearable and easy to work in. Then in 2006 I began developing a (pink) silver colored metal while blending different percentages of elements I came up with this white color alloy. After many tests I found that with this small percentage of pure gold, it gives Karatium White a little nicer polish and luster than traditional silver.

Continuing tests of this new alloy proved very positive to casting, fabricating and polishing as used in the jewelry industry. As designer of this new alloy I felt it mandatory that any new well priced alloy have the same characteristics as traditional sterling silver and 14 karat white gold, this to enable any craftsmen to start working in this alloy immediately. After the final development of this new alloy I made contact with the Jewelers Vigilance Committee and learned that because this metal is less than 10 karat and has less than 900 fine silver I could not use the word gold or silver in correspondence to any name for this alloy. Hence the name Karatium White that is a made up name that I have trademarked. Karatium actually comes in 2 additional colors Yellow and Pink, and a Sterling version which I have also submitted for Patent Application
