Gold necklaces are typically marked with a hallmark that indicates the purity of the gold, often expressed in karats (e.g., 14K, 18K) or parts per thousand (e.g., 585, 750). Additionally, the hallmark may include the manufacturer's mark or country of origin to provide authenticity and traceability. These markings are usually found on the clasp or a small tag attached to the necklace.
