The "906" stamped on a brooch typically indicates the purity of the metal, specifically that it contains 90.6% silver, which is equivalent to sterling silver. This marking is part of the system used to denote the quality of silver in jewelry. Additionally, it may also refer to a particular manufacturer's code or design number, depending on the context and origin of the piece. Always consider consulting a jeweler for precise identification.
