The term describes a specific manufacturing process where a substantial layer of 14-karat gold is mechanically bonded to a base metal, often brass or copper. This layer, constituting at least 5% of the item’s total weight, offers a surface with the appearance of solid gold, while the base metal provides structural integrity. As an example, jewelry described using this term features a thick outer layer of gold, offering considerable durability and a rich color.
The significance of this manufacturing method lies in its provision of a more affordable alternative to solid gold. It delivers many of the aesthetic benefits and a degree of the durability associated with higher-karat gold pieces. Historically, this technique gained popularity as a way to create accessible and attractive items while conserving precious metals. The resulting products offer a balance between cost and quality, rendering them attractive to a broader market segment.
