"Gold-filled jewelry is jewelry composed of a solid layer of gold (typically constituting at least 5% of the item's total weight) mechanically bonded to a base of either sterling silver or some base metal. The related terms "rolled gold plate" and "gold overlay" may legally be used in some contexts if the layer of gold constitutes less than 5% of the item's weight.[1][2]
Most high quality gold-filled pieces have the same appearance as high carat gold, and gold-filled items, even with daily wear, can last 10 to 30 years. The layer of gold on gold-filled items is up to 100 times thicker than that produced by gold electroplate (sometimes stamped HGE for "heavy gold electroplate" or HGP for "heavy gold plate", which have neither of them any legal meaning and indicate only that the item is gold plated)."
