| Gold Plated and Gold Filled Definitions With precious metal prices at an all-time high, I would like to explain the difference between gold filled vs. gold plated.
Gold Plate What is Gold Plate? – Gold plating is a minuscule layer of solid gold applied to a brass base. How miniscule? With jewelry, we’re dealing with microns. For comparison’s sake, the standard sheet of paper is 100 microns thick, while a piece that’s gold plated can have just 1 micron’s worth of gold on top. The plating does not compose any measurable proportion of the products total weight. It is estimated to be 0.05% or less of the metal product. Gold plating will generally wear off rather quickly and expose the brass base product. DO NOT wear your gold plated jewelry in the shower or hot tub.
Gold Filled Gold Filled is constructed in two or three layers. The core metal is jewelers’ brass. A gold alloy is then bonded to one or both surfaces of the brass core with heat and pressure. Unlike plated (aka electroplated or "dipped") metals, Gold-filled is legally required to contain 5% or 1/20 gold by weight. This 5% is then described by the karatage of the gold alloy.
The difference between gold plated and gold filled jewelry is that gold filled has a thicker layer of gold, with a stronger bond between the gold and the base metal thanks to a production process that includes heat and pressure. This bond with the base means the finish is less prone to tarnishing and wear. |
