Gold Types and Gold Technology
Gold Filled, also called Gold Overlay, refers to a layer of at least 10-karat gold that has been permanently
bonded by heat and pressure to one or more surfaces of the support metal, then rolled or drawn to a prescribed
thickness. The karat gold must be at least 1/10 of the total weight.
Gold Plate means that a layer of plating of 10-karat gold or better has been bonded to a base metal. The karat
gold content may be less than 1/20, but it must be properly identified by weight in terms of total metal content.
Gold Leaf is just gold plating that’s been pounded and applied by hand.
