What does sp mean stamped on a bracelet?

The "SP" stamped on a bracelet typically stands for "sterling plated" or "silver plated," indicating that the piece is made with a thin layer of silver over a base metal. This designation helps consumers identify the quality and material composition of the jewelry. It's important to note that items marked with "SP" may not have the same value or durability as solid sterling silver. Always check for additional markings to confirm authenticity.
