Please help me find a rosary lost in Medellín

I'm Carolina. I lost my late grandfather's rosary on Friday, somewhere between the park 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 grandfather. 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. Thank you to everyone who has looked.
