Details are unknown. I have included many photos of the engravings and details, so please take a close look and make your own judgment. The ring seems to have some dullness, but it might become beautiful after cleaning. I think it's about size 9. The ring is thin, so it makes your fingers look beautiful and has a feminine design. Please make your own assessment and purchase only if you are satisfied. I will adjust the price at my own timing, so no price reduction is possible. There is no case. I have included everything I know in the photos, so please understand that no returns or refunds are accepted.
