Gold diamond ring, 14k yellow gold, size 7

I lost my gold diamond ring yesterday around 3pm near the Grand Rapids Public Museum on Museum Row. It's a 14k yellow gold band, size 7, with a single small diamond set in a simple bezel. There's a tiny inner inscription 'M.B.' and a faint bend along the outside from daily wear. The ring has sentimental value—it's a gift from my grandmother, and I really need it back. If anyone found it, please message me; I can offer a modest reward and can meet downtown to pick it up.
