When purchasing jewellery a more economical than solid gold but still beautiful option is a gold filled piece. It is composed of a solid layer of gold mechanically bonded to a base metal.
It won’t tarnish and will not rub off or turn colours. Wearers who are sensitive to certain metals can wear gold filled without worries of an allergic reaction. Although the layer of gold in gold filled pieces varies depending on the manufacturer it is in all cases significantly thicker than regular gold plating.
