Silver engraved ring, lost near Belfast City Hall

I lost my silver engraved ring yesterday around 3pm near Belfast City Hall on Donegall Square West. It's a sterling silver band, about size 7, with a smooth, polished finish and a tiny blue sapphire on the bezel. Inside the band the initials 'MF' are engraved, and there's a small scratch along the outer edge from daily wear. It has real sentimental value—it was a gift from my grandmother, who passed away last year, and I miss it every day. I really need it back. If someone found it, I’d be forever grateful and I’d arrange a meetup in the City Hall area or nearby if possible.
