Gold-filled jewelry comprises a base metal, typically jeweler’s brass, mechanically bonded with a layer of gold. The gold layer must constitute at least 5% of the item’s total weight. Due to the presence of base metals within the construction, the surface may darken or discolor over time.
The longevity and appearance of gold-filled items are valued for their affordability relative to solid gold. Historically, this construction method provided a more accessible option for individuals seeking the aesthetic of gold without the substantial cost. It is a practical alternative, offering reasonable durability under normal wear conditions.
