Gold Plated Brass Gold plated jewelry means that a layer of gold is attached to the surface of a base metal. At En Route, we only use genuine gold for our plating. Brass is a hard metal, after integrated with gold, it helps with preserving the shape of the jewelry. Our gold plating is very sturdy, however you should still try to avoid contact with chemicals and moisture to keep your jewelry in mint condition. If your jewelry comes into contact with water, it is recommended that you dry it with a soft cloth or tissue, as moisture can damage surfaces and cause them to rust.
