A specific type of jewelry comprises a base metal, typically sterling silver, coated with a layer of gold. This layering process differentiates it from gold-plated items, as the gold layer must meet a minimum thickness requirement. For example, a piece labeled as this type of jewelry will have sterling silver as its core material, covered by at least 2.5 microns of gold that is at least 10 karats fineness.
This type of material offers a balance between affordability and the aesthetic appeal of solid gold. It allows individuals to enjoy the look of gold jewelry without the higher cost associated with pure gold pieces. Historically, this method provided an accessible alternative for those seeking quality jewelry that was more durable than simple gold plating, establishing itself as a respected option in the jewelry market.
