Please help me find a signet ring lost in London

I'm Natalie. I lost my late mother's signet ring last weekend, somewhere between the station and the bus stop. It's a small silver locket with a photograph inside. It isn't valuable to anyone else, but it's one of the last things I've of mother. 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.
