What does HP stamped on jewelry mean?

HP stamped on jewelry typically stands for "Heavy Plated," indicating that the piece is made from a base metal that has been coated with a substantial layer of gold or other precious metals. This stamp signifies that the jewelry is not solid gold but is designed to have a more luxurious appearance without the higher cost. It is important to note that the durability and longevity of heavy plated jewelry can vary based on the thickness of the plating.
