The gold is applied to a base metal (brass in this case) in a very thin layer. Gold plated jewelry is an affordable option to solid gold. You can lengthen the life of the gold layer by removing your jewelry when swimming in pools and especially the ocean. Also while exercising. Salt and chemicals break down the gold layer. Do not use a polishing cloth with chemicals to clean plated jewelry as the gold will rub right off.
