This is a magatama (comma-shaped bead) made of Kon-zawa jade from Itoigawa, from Anahita Stones. The size is 3 cm. It was originally sold as a set with an appraisal certificate, but the certificate went missing during a big cleaning. This listing is for the magatama only, but I have confirmed that it has not undergone resin impregnation treatment. *The pattern appears slightly darker in the photos. - Material: Stone - Color: Blue - Shape: Bean-shaped - Feature: Drilled hole for hanging Thank you for viewing.
