14k yellow gold ring with sapphire

I lost my 14k yellow gold ring yesterday around 3pm near the Aberdeen Public Library on 2nd Ave NE, in Aberdeen, Northeast SD, right outside that little coffee shop by the corner. It's a slim 3mm band with a brushed finish and a tiny bezel-set sapphire on top. The inside of the band is engraved with 'A.K.' and it's gotten a few scratches from daily wear. It meant a lot to me—the ring was a gift from my grandmother—and I really need to get it back. If anyone finds it, please contact me via email at [email protected].
