Gold-plated jewelry usually has one-tenth of the gold alloy by weight that gold-filled jewelry has. Its affordability makes it popular, but the gold alloy coating is likely to wear off over time. Electroplating is a modern gold-layering technique that uses electrical currents to charge the base metal. When they attach to the base metal, a gold layer is formed.
