This necklace features a K18 open heart design with a platinum base and a single diamond. I loved the cute design and purchased it at a department store. I enjoy collecting and looking at my jewelry, so I've only worn this necklace a few times. I'm offering it for sale to someone who will appreciate it. It's a beautiful item, almost new, but I ask that you understand it is a pre-owned item. Materials: K18, pt900 Decoration: Diamond
