A gold alloy plate made by soldering, brazing, welding or other means that is not less than 10Kt fineness, where the plating constitutes at least 1/20th of the weight of the metal in the entire article. The term must be preceded by the karat fineness of the plating, such as 14Kt Gold-Filled. When using the term gold overlay, manufacturers are permitted to use a layer of gold that is less than 1/20th the weight of the entire piece, but they must stamp the proportion of the gold layer on the jewelry.
