Karatium white

Abstract

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).

1 . A white metal alloy of 2.4 Karat that has a good white (silver) color and resist tarnishing and the discoloration of skin. 
   
   
       2 . Has all of the same jewelry workability as sterling and 10 karat white gold or higher.
