I found this onyx? hematite? necklace while cleaning out my parents' house. It's part of my grandmother's jewelry collection. The design is suitable for men as well. As it's either onyx or hematite, it's magnetic and sticks together like a magnet, as shown in image 5. Only the round beads stick together. There is verdigris at the base of the clasp. Length: 40cm Please refrain from purchasing if you are not familiar with antiques or vintage items, or if you are overly sensitive to imperfections.
