What materials are gold plated earrings made out of?

Gold-plated earrings are typically made from a base metal such as brass, copper, or stainless steel, which is then coated with a thin layer of gold through electroplating or physical vapor deposition. This process gives the earrings a gold appearance without the cost of solid gold. The thickness of the gold layer can vary, affecting the durability and longevity of the plating. It's important to handle gold-plated earrings with care to prevent wear and tarnishing.
