A Burberry ring purchased at a department store in Osaka. I asked AI because I lost the box and warranty. The inner diameter of the ring is 1.8 cm (18mm), which is approximately size 16 to 17 in the Japanese ring size standard. It might become beautiful if you wipe it with a special silver polisher. (^-^) I would be happy if someone who can take care of it would purchase it (^-^) Vintage
