Our 14 Karat Gold is composed of 58.3 percent pure gold and is ideal for fine jewelry. Other alloys, such as copper, are mixed in with the gold to give more of a red warm hue. This also give the metal strength. Since gold is a natural element, it is very durable. We do recommend removing the jewelry if it may come in contact with chemicals. To clean gold jewelry, use warm water and detergent free soap and a soft brush.
