To determine if a gold necklace is real, you can start by checking for a hallmark or stamp indicating the karat (such as 10K, 14K, 18K, etc.). Additionally, you can perform a simple magnet test, as real gold is non-magnetic, or consider having it professionally tested with an acid test or electronic gold tester for more accuracy.
