GM1 typically refers to a specific quality mark or manufacturer's code on jewelry, indicating the type of metal used or the jewelry's design series. It may also signify that the piece is made from a particular alloy or has been produced by a specific brand. Understanding these markings can help consumers assess the quality and authenticity of the jewelry. Always consult with a jeweler for precise interpretations of specific markings.
