Gold diamond ring with A.J. engraving

I lost my 14K yellow-gold ring yesterday around 3pm near the National Aquarium entrance on Light Street, Baltimore. It's a delicate size 6 with a small solitaire diamond set in a thin bezel and a brushed finish. Inside the band there's a tiny engraving 'A.J.' and it shows a few light scratches from daily wear. The ring was a gift from my grandmother and holds a lot of sentimental value—I'm really hoping to get it back.
