Items described as “14kt gold filled” comprise a base metal, typically jeweler’s brass, with a layer of 14 karat gold mechanically bonded to the surface. This bonding process involves heat and pressure, creating a durable outer layer of gold. For example, a gold filled chain will exhibit the appearance of solid 14 karat gold while containing a significantly lower proportion of the precious metal.
The appeal of this material lies in its balance of affordability and aesthetic qualities. It offers a cost-effective alternative to solid gold, providing a similar visual appeal and longevity under normal wear conditions. Historically, it served as a more accessible option for adornment, allowing a wider segment of the population to enjoy gold’s aesthetic benefits without the higher price point of solid gold pieces.
