A gold overlay is a layer of metal that covers another base metal. Gold overlay can be found on anything from picture frames to mirrors.
Jewelry with a gold overlay can possibly turn your skin green. This is determined by if you have a skin allergy to the metal under the overlay.
Gold is a precious metal that is often used to make jewelry and has a higher value than gold overlay. Gold overlay, also known as gold filled, is made by bonding a layer of gold to a base metal. You can distinguish between the two by looking for markings such as karat stamps or "GF" for gold filled on the jewelry piece.
