What does 14k plat lid stand for inside your ring?

A "14k plat lid" inside your ring indicates that the ring has a base metal of 14-karat gold with a plating of platinum on top. The "14k" signifies that the gold is 58.3% pure, while "plat" refers to the layer of platinum, which is a more durable and tarnish-resistant metal. This combination enhances the ring's aesthetic appeal while providing some of the benefits of platinum. However, the plating may wear off over time, revealing the gold underneath.
