The term describes a specific type of jewelry finish. It denotes sterling silver that has been coated with a layer of gold. The “14k” indicates the gold’s purity; 14 karat gold is an alloy containing 58.3% pure gold, combined with other metals to increase its durability. The gold layer must meet a minimum thickness requirement, typically 2.5 microns, to be legally considered this type of finish.
This finishing technique offers a cost-effective way to achieve the look of solid gold jewelry while utilizing the more affordable base metal of sterling silver. The result is a piece with a precious metal appearance at a lower price point. Historically, this process has been used as an alternative to solid gold construction, allowing for more accessible luxury.
