This is a designer necklace made with approximately 9.0g of platinum 850. (Stamped with pt850) Made with high-quality platinum 850. It has a simple and elegant design. I received it as a gift from my grandmother, but I only tried it on once and have kept it stored since then. It is relatively clean, but the box has some yellowing because I received it quite a while ago. Please check the photos. As it has been stored by a private individual, there may be some overlooked scratches or stains. Please refrain from purchasing if you are sensitive to such things. Returns are not accepted to prevent product substitution, so please understand. Material: Pt850 Weight: Approximately 9g Marking: Pt850
