This is a platinum Pt.850 screw chain necklace. It's a sparkling and very beautiful chain necklace. I purchased it before and wore it a few times, but I think it's in good condition. I'm selling it to someone who likes it, as my taste has changed. Length: Approximately 40cm Chain width: Approximately 2mm Stamped with the Japan Mint mark ♠ Please refrain from purchasing if you are nervous about used items. ♠ There is no case, so it will be shipped in simple packaging.
