The gold-plated layer of gold-plated jewelry is generally K gold, which contains a certain amount of silver in addition to pure gold. After silver reacts with some volatile industrial waste gas in the air, a black silver sulfide film will be formed on the surface, which will make the gold-plated watch lose its golden luster. Therefore, wearing gold-plated jewelry should avoid contact with chemicals and waste gas, such as gas, liquefied gas and sulfur soap, and always keep gold-plated jewelry dry and clean. It is best to wipe it with a flannel once a week.
