Please help me find a brooch lost in Edinburgh

I'm Elena. I lost my late grandmother's brooch on Tuesday, somewhere between the church and the bus stop. It's a plain ring worn smooth with age. It isn't valuable to anyone else, but it's one of the last things I've of grandmother. I've retraced my steps twice and asked at the shops and the bus company. If you've found it, or you have a bin, a bench or a hedge you could check, I'd be grateful. A finder's thank-you is waiting. Please use the offer button here rather than sharing any numbers publicly.
