What is Gold-Filled?
Gold-filled is a United States layered gold product that is gaining popularity throughout the Americas, Asia and Europe. It is a quality material that is common in all types of jewelry. The product is easy to care for and will usually maintain its golden shine for a lifetime.
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. The bonded raw material is then sold as sheet or wire to jewelry manufacturers for use in designs.
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. Most gold-filled is 12kt or 14kt gold-filled. It is most accurately labeled with the karatage, the “/” symbol, and then 20 to reflect this construction. Products are identified as 14/20 Gold-filled or 12/20 Gold-Filled; alternatively, 14kt Gold-Filled or 12kt Gold-Filled are also acceptable.
Care and Cleaning
Gold-filled does not de-laminate or peel like plated products. Nor does it tarnish as readily as silver. Many owners find that they never have to clean gold-filled items at all. However, from time to time your jewelry may become dirty from everyday wear. To clean gold-filled it is best to use mild soap and water. Hot weather and water will not damage the material.
Gold-filled cannot be melted because it is a layered product. Similarly, exposure to chemicals or acids will damage the gold layers and erode the product’s integrity. Gold-filled is not recommended in extremely humid environments where there are also high levels of pollutants in the air. This is not a problem in any US states we know of, but we have had reported problems in South-Central Mexico and parts of Asia.
Comparison with Other Gold Products
Solid Gold – Solid gold is an alloy that is described with the karatage of pure gold. Pure gold is 24kt. However, it is much too soft to hold its shape or wear well. Therefore, it is mixed or alloyed with other metals to make it harder and easier to work with. Karatage refers to the alloy’s purity. For example, 8 karat gold is 8/24 pure gold or 33.3% pure. Gold-filled is not the same as solid gold. It is a layered alternative product. The gold-filled karatage only refers to the gold layers that compose 5% of the product on the surface.
Gold Plate – Gold plating is a miniscule layer of solid gold applied to a brass base. 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 wear off rather quickly and expose the brass base product. It does not stand up to heat, water or wear over time.
