An item of jewelry fabricated by bonding a layer of gold alloy to a base metal core, usually brass or copper. This process creates a more affordable alternative to solid gold, offering the aesthetic appeal of gold without the associated cost. For example, a 14k gold filled necklace features a specific proportion of 14 karat gold bonded to the underlying metal.
This type of jewelry offers enhanced durability compared to gold-plated alternatives due to the significantly thicker layer of gold. It provides a viable option for individuals seeking a balance between price and longevity. Historically, this manufacturing technique has been employed to extend the availability of gold’s aesthetic qualities to a wider consumer base, making it a popular choice across various eras.
