The "GM" stamp on a ring typically indicates that the piece is made of gold and is manufactured by a specific company or brand, often signifying "Gold Mark" or the initials of the manufacturer. This stamp is used to denote the quality and authenticity of the gold, which can vary in karat content. It's important to consider the context of the stamp, as different manufacturers may have their own specific meanings associated with the initials. Always verify with a jeweler for accurate identification and appraisal.
