This term describes a jewelry fabrication method where a layer of 18 karat gold is applied over a base of sterling silver. The resulting item combines the aesthetic appeal of high-karat gold with the structural integrity and affordability of sterling silver. For instance, a necklace crafted using this technique would exhibit the rich color and luster of 18k gold on its surface, while the underlying sterling silver provides durability and reduces the overall cost compared to a solid 18k gold piece.
Employing this method offers several advantages. It allows for the creation of more accessible luxury items, making the look of gold jewelry attainable to a broader audience. Sterling silver’s inherent strength enhances the piece’s longevity, protecting the relatively softer gold layer from wear and tear. Historically, this technique has been utilized to create decorative objects and jewelry, balancing precious metal aesthetics with cost-effectiveness.
