I stopped in Gold Star Gold Buyers today to have them take a look at a pair of earrings to verify the stone, and they were so friendly and helpful! The woman helping me did a couple of tests on the earrings to establish what the stone and metal was, and was extremely knowledgeable and shared a lot of information with me! She didn't have to spend so much time helping me, I wasn't spending any money, she just genuinely wanted to help me! Seems like a very trustworthy and professional business!
