This is a crystal necklace I purchased during a trip to Noto a long time ago. I lost the certificate of authenticity, but I had it until recently. I believe it's genuine because the certificate and two accompanying crystals were in the accessory box until recently. The clasp on the back is stamped with "Silver," but it's small and difficult to read. I'm selling it at a low price because I don't have the accessory box or the certificate. - Material: Crystal - Clasp: Metal clasp Free shipping via Mercari Yu-Packet Post.
