A keepsake lost in Rabat: any news would mean the world

I'm Rémi. I lost my late father's signet ring about a week ago, somewhere between the church 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 father. 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. Every share helps. Thank you.
