Gold necklaces are typically marked with a hallmark or stamp that indicates the purity of the gold, often in karats (such as 10K, 14K, 18K, or 24K) or in parts per thousand (e.g., 750 for 18K). The marking may also include the manufacturer's trademark or logo, and sometimes the country of origin. These markings are usually found on the clasp or another discreet part of the necklace.
