Gold filled jewelry comprises a base metal, such as brass or copper, mechanically bonded with a layer of gold. The gold layer, typically 5% or more of the item’s weight, is significantly thicker than that found in gold plated items. As an example, a gold filled chain will have a substantial layer of gold bonded to its core metal, offering durability and a look similar to solid gold.
The appeal of this type of jewelry lies in its balance of cost and quality. It offers a more affordable alternative to solid gold, while providing enhanced durability compared to gold plating. Historically, gold filled jewelry became popular as a way to make precious metal aesthetics accessible to a wider consumer base. Its longevity contributes to its perceived value and makes it a suitable option for everyday wear. The increased thickness of the gold layer allows for greater resistance to wear and tarnish.
