It has been missing for a long time, but we have found it! 2026.01.31 ----- After investigating, It is a ring from the white porcelain jewelry brand "akari" by Akari Sato. I feel that white porcelain jewelry is cool and suits Japanese skin better than metal jewelry. I bought it at a select shop to use as an accent on my husband's glasses, but I haven't used it, and I haven't used it as a ring because I'm afraid it might break. Purchased around September 2016, only tried on at home. How about using it as a ring, or threading a string through it and attaching it to a bag? ------------ [Size (inner diameter of the ring)] *It is oval. Approximately 17mm at the widest part Approximately 15.6mm at the narrowest part ★Measured with calipers, but please consider it approximate as the cut is not straight. ★It fits perfectly on Mongoru's left index and ring fingers. ・Mongoru's left index finger ring size Size unknown (probably 9-10) ・Mongoru's left ring finger ring size Size unknown (probably 8-9.5) ★Confirmed with a ring sizer.
