The presence of a thin layer of gold on a base metal defines items described as gold plated. This process, electroplating, deposits a microscopic layer of gold onto a more affordable material such as nickel, silver, or copper. A common example is jewelry manufactured from a base metal and then coated with a thin layer of gold to provide a gold-like appearance.
The appeal of this process lies in its ability to impart the look and feel of solid gold at a significantly reduced cost. Historically, this technique has allowed for broader accessibility to gold-appearing items, particularly in decorative arts and adornment. The economic advantages are considerable, making it a viable option for applications where the visual aesthetic of gold is desired without the substantial investment associated with pure gold.
