To determine what kind of gold a necklace is, check for hallmarks or stamps, usually located on the clasp, indicating the gold's purity (e.g., 10K, 14K, 18K) or type (e.g., "GP" for gold-plated). Additionally, consider having the necklace tested by a professional jeweler who can assess its composition using specialized tools.
