Color: Gold Material: K18 This is an 18k gold ring with a butterfly design. It was purchased from a jewelry store in Hiroshima Prefecture. Size: 9.5 Weight: 3g. The size and weight were measured at the jewelry store. Length: Approximately 2cm Although it may be difficult to see in the image, it is stamped K18 on the back. I liked this design and wore it, so there are some minor scratches. Please refrain from purchasing if you are looking for perfection. It will be shipped in the original box. Returns are not accepted to prevent product substitution.
