The stamp "CU" on jewelry typically indicates that the piece is made of copper. It can also suggest that the item is composed of a copper alloy. In some cases, it may be used to denote the quality or purity of the metal, though it's less common than other metal stamps like "925" for sterling silver or "585" for gold. Always verify with a professional if you're unsure about the meaning of specific jewelry stamps.
