Someone is trying to sell me a gold necklace. I do not know the person well and they do not work for any store or anything like that. The person is trying to sell me a 14k gold necklace. I want to make sure that the gold is real before I buy it. What are some quick and simple ways to test the gold to see if its real. Please respond with serious answers. Thanks in advance to all who answer.
