It is also possible to determine whether a piece of gold is real or gold plate by checking the piece for a manufacturer's hallmark and karat stamp. If the item is missing the stamp, it is most likely gold-plated. The difference between solid gold and gold plating is simple. Solid gold is gold in its purest form, and gold plate is a light coating of gold over metal. Gold-plated jewelry is often made with silver or copper and tends to leave a greenish stain on the skin. Gold-plated jewelry also produces a powdery gold substance as time wears on and the gold-plated coating begins to deteriorate.
