The term describes jewelry construction where a base metal of sterling silver is covered with a layer of 14 karat white gold. This process, known as plating, involves depositing a thin coating of white gold onto the silver surface through electrochemical means. This results in an item that presents the visual appearance of solid white gold while utilizing a less expensive and more malleable core material.
This manufacturing approach offers several advantages. The use of silver as the base provides durability and allows for intricate designs, as it is more easily worked than gold. The outer layer of white gold contributes the desired color and luster, enhancing the aesthetic appeal. Furthermore, it provides a degree of tarnish resistance to the silver, although the silver can still tarnish over a long period of time if the white gold coating wears off. Historically, such techniques have been employed to create more affordable luxury items, making the appearance of precious metals accessible to a wider audience.
