What is the difference between gold-filled and gold-plated jewelry?
The difference between gold-fill and gold-plate is in the amount of gold. Gold-plated pieces have a very thin layer (seven-millionths of an inch) of gold, while 14K/20 gold-filled products must have at least one-twentieth of their entire weight in 14K gold. This means that gold-plated items, while cheaper, will not last as long. Eventually the thin gold layer will rub off. Gold-filled items, however, will remain gold for a lifetime if cared for properly.
