Silver sapphire ring, Nottingham, East Midlands

I lost my silver sapphire ring yesterday around 3pm near the Victoria Centre entrance in Nottingham city centre. It's a sterling silver band about 6mm wide with a small blue sapphire bezel setting. Inside the band there’s a tiny crescent moon engraving and the initials 'M.P.' that you can't see from the outside. The ring has huge sentimental value and was a gift from my grandmother, so I’m really hoping it’s found and brought back. If found, I’d be forever grateful.
