The process involves combining gold with other white metals to achieve a silvery-white appearance. This alloy is commonly created by mixing gold with metals such as palladium, platinum, nickel, or manganese. The specific proportions vary depending on the desired color and properties of the final product. For instance, an alloy containing nickel may exhibit a slightly yellowish tint, while palladium-based alloys tend to be whiter.
The resulting material offers a durable and aesthetically pleasing alternative to pure gold, lending itself well to jewelry applications. Its strength and resistance to tarnish are significant advantages. Historically, the development of this alloy allowed for the creation of more affordable platinum-look jewelry when platinum was scarce or expensive. It also provided a base material better suited to rhodium plating, further enhancing its whiteness and brilliance.
