Gold Filled Jewelry Differ From Gold Plated Jewelry
The most common method of gold plating is electroplating. Electroplating gold onto jewelry is more complex than the method for making rolled gold and gold filled.

For most gold plating, a microscopic layer of gold is adhered to a base metal using an electric current. This current carries positively charged gold ions and adheres them to a negatively charged base metal.
Sometimes this layer is so thin that it can be very easily rubbed off. Gold filled jewelry is much thicker and therefore much more durable. Because of the difference in gold content, gold filled jewelry is significantly more expensive than gold plated jewelry. Some antique gold filled jewelry has such high gold content that it can be worth as much as some solid gold pieces.
