14k gold ring with small diamond, sentimental

I lost my 14k yellow gold ring with a small diamond yesterday around 3pm near the Starbucks on Broadway in downtown Chico. It's a size 6.5, with a brushed finish and a tiny diamond prong-set along the top; the inside has '14K' and the initials 'P.R.' engraved, plus a faint scratch along the outer edge. This ring is a family heirloom from my grandmother, so it means a lot to me and I’m really hoping to get it back. If you found it or have any info, drop me a message here—I’d be incredibly grateful.
