What does plat 14k mean stamped on a cuff link?

The stamp "plat 14k" on a cuff link indicates that the piece is made of 14-karat gold that has been plated with platinum. This means that the cuff link has a base metal, often less expensive, which is coated with a thin layer of platinum for added durability and aesthetic appeal. The presence of both metals suggests a combination of value and a luxurious appearance, but it is important to note that the underlying metal is not gold itself.
