The marking "JM375" on a gold ring indicates that the metal is 375 parts per thousand pure gold, which corresponds to 9-karat gold. The "JM" likely represents the initials or logo of the manufacturer or jeweler who created the piece. This marking helps identify the quality and authenticity of the gold used in the ring.
