Gold Filled products should remain gold for the life of the product because of how Gold Filled is manufactured. A layer of 14K gold is mechanically bonded with heat and pressure to one or more surfaces of the supporting base metal then rolled or drawn to a given thickness. Industry standards for the quantity of gold must be at least 1/20th by weight of the total product.
