This technique is best suited to necklaces or earrings, where the durability of the coating is less crucial.įor more information see our Metals Info and Care Guide. Gold filled, gold plate, and electroplate items have thinner layers of fine gold applied over silver or a base metal such as bronze or steel, and contain less gold content than vermeil.The gold is generally 14, 18 or 24 karat, and frequently specified. It requires a layer of gold at least 2.5 microns thick (approximately 100 millionths of an inch). The rhodium finish on white gold will wear off over time depending on how the jewelry is worn, cared for and cleaned. Rhodium is in the platinum family, and therefore tarnish resistant. White gold is routinely coated with a rhodium finish. White gold is created by mixing other alloys with the pure 24K gold.The 18 karat gold standard is most typical of Italian and other European countries. Gold content is described based on the amount of pure gold compared to the alloys added.With recent changes in federal guidelines, an item that is called 'gold' may have as little as 1 karat of gold in the piece.In the U.S., recent changes to FTC guidelines now allow an item to be described as 'gold' with a modification even if there is only 1 karat of gold in the item (1/24, or 41/1000, parts gold). There are specific definitions, according to the 'fineness' (the amount of pure gold it contains). laws and Federal Trade Commission guidelines govern the way gold jewelry must be described. When you see several pieces of jewelry that all look similar, yet are priced very differently, the fineness of the gold may account for the vast differences in pricing. Sometimes jewelry is characterized as gold, but really contains very little gold, or none at all. When you are looking at jewelry, it's important to know the quality of what you buy.
