A specific type of jewelry component consists of a base metal, typically brass, bonded with a layer of 14 karat gold. This bonding process involves using heat and pressure to adhere a substantial layer of gold to the base metal. As an example, this material is frequently used in the production of necklaces, bracelets, and other adornments.
This construction method offers a balance between the desirable qualities of gold, such as its appearance and tarnish resistance, and affordability. Historically, it provided a more accessible alternative to solid gold pieces, allowing a wider consumer base to enjoy the look of gold jewelry without the higher cost. The durability of the gold layer contributes to the longevity of the item.
