This is a Tsumami-zaiku crane ring. I bought it because it's handmade. I haven't had a chance to use it myself, but I think it would be lovely for weddings, receptions, Coming-of-Age ceremonies, or other celebratory occasions. While it's a ring, it could also be skillfully used as a hair accessory. Size when viewed from above: 6x6 Ring size: Approximately 8.3
