Gold diamond ring, 14k, sentimental, lost near Bridge Street

I lost my gold diamond ring yesterday around 3pm near Bridge Street Town Centre in Huntsville. It's a thin 14k yellow gold band with a tiny round diamond, and the inside has faint initials AR plus a crescent moon mark. It was a gift from my grandmother, so it means a lot to me and I’ve been anxious since it disappeared. If anyone found it, email me at [email protected]—I’d be so grateful to hear from you.
