Definitions for "Gold-Plated"
Base metal which has been bonded with at least 0.0025 mm of gold. Not as durable as alloyed gold or gold-fill. With moderate to heavy use, gold-filled and gold-plated jewelry will eventually lose their coating, leaving the base metal exposed.
Gold-plated metal has a very thin layer of gold on the surface, usually applied by the process of electroplating.
See Gold-Filled.
