Dear Rodney Horton, we have received your feedback. However, I need to emphasize that our products' advertisement and products' details clearly indicate that the products we sell are all 18K pure gold jewelry, not the 24K you think. Firstly, when we first communicated, I clearly told you: "we are a manufacturer of 18K real gold jewelry." Secondly, because you told me at the time of purchase that you wanted an 18K logo, I assumed you knew that our product was 75% gold, not 100%. Finally, the chain was broken because the institution you took to did the destructive testing on the product. If possible, could you please provide the report after the test. We can guarantee that our products are 100% 18K pure gold jewelry. Maybe because of the misunderstanding caused by our communication brought you a bad experience, I'm so sorry about that!!
