Agate bar-type earrings. Currently, a similar design is available in K10, but this is the older type made of K18 material. Material: K18, Diamond Size: 1cm x 0.1cm (approx.) Retail Price: 79,200 yen Accessories: Box Although the certificate is lost, these are genuine items purchased at a store in Tokyo. Maintenance should be available at the store. I am selling these because I no longer have the opportunity to wear them. The K18 version should be difficult to obtain now, so if anyone is looking for them, please consider purchasing them.
