An item of jewelry comprised of a base metal, such as brass or copper, covered with a thin layer of gold electroplated onto its surface. The “18k” designation indicates that the gold layer is created from an alloy containing 75% pure gold, mixed with other metals to increase its durability. This technique provides the visual appeal of a solid gold piece at a lower cost. As an example, a band fashioned from sterling silver and then coated with a fine layer of 18k gold would be categorized under this description.
This construction method offers a cost-effective alternative to solid gold jewelry. The practice of plating allows individuals to enjoy the aesthetic of precious metal without the significant investment required for fully gold items. Throughout history, various plating techniques have been utilized to enhance the appearance and value of objects, demonstrating a long-standing desire for accessible luxury.
