The stamp "18kthg" on a ring indicates that the piece is made of 18-karat gold and may contain a specific alloy or combination of metals, with "thg" possibly referring to a particular manufacturer or standard. 18-karat gold consists of 75% gold and 25% other metals, making it durable yet valuable. It's essential to verify the authenticity of the stamp and the quality of the gold when purchasing jewelry.
