The gold marking on a ring, often referred to as a hallmark, indicates the purity of the gold and sometimes the manufacturer. Common markings include numbers like "10K," "14K," or "18K," which represent the karatage and therefore the proportion of gold in the alloy. These markings can also include other symbols or letters that identify the maker or certify the metal's authenticity according to specific standards.
