Gold-plated jewelry consists of a lower-quality base metal coated with a very thin layer of gold through a chemical process, while gold-filled jewelry has a thicker layer of gold bonded to a base metal through heat and pressure. Although both gold-plated and gold-filled jewelry consist of a base layer covered with gold, they differ in the process used to attach the gold and the thickness of the gold.Know More
Copper and silver are often electroplated with gold. Gold-plated silver is called silver-gilt. Gold-plated jewelry is subject to tarnish, and the gold wears off more quickly than in gold-filled jewelry. Brass is the most common base metal used for creating gold-filled pieces. High-quality gold-filled pieces are difficult to distinguish from 14-carat gold.
