Gold Plated
Gold plated jewelry is made by using electricity or chemicals to deposit and bond a very thin layer of gold over another metal. This process creates a layer as thin as 1/1000 to 3/1000 of an inch of gold over a more affordable metal, usually silver or copper.
Determining exactly how long a gold plated piece will last can be difficult because it is affected by a number of factors. If the plating is relatively thick, it may last longer than a piece with thin plating. Pieces that are worn on a daily basis will also tend to wear out more quickly because it is often coming in contact with the outside world and elements that can cause damage.
On average, gold plated jewelry can last about two years before the gold plating begins to tarnish and wear down.
