Wedding ring found

I found a diamond ring with a gold band on the ground Monday evening (a national holiday) at 5:30 at the intersection of Shijo and Kawaramachi streets, the busiest intersection in Kyoto. It seems to be a wedding ring, stamped with a year beginning 18XX, and has other distinguishing features. Spread the word if you know anyone visiting or living in Kyoto who may have lost one. The Kyoto Police department has it. I'm going to try to get the word out to local neighborhoods. I imagine there is a heartbroken old lady somewhere who wants it back, and I'd like to get it to her.
