Gold plating is a method of covering a metal with a thin layer of gold. The underlying metal is usually cheaper, but sturdy and durable, so the gold plating provides a far more attractive finish than the core metal. Gold plating is done via a process known as electroplating. It differs from gold-filled, which is composed of a higher concentration of high-quality gold. Gold plating can be applied to just about any type of metal as long as the metal has a conductive surface such as silver and copper.
