Silver band ring with small diamond, engraved inside

I lost my silver band ring yesterday around 6pm near the New River Valley Mall parking lot, by the Food Court entrance off US-460. It's a slim silver band, about size 6, with one small round diamond that catches the light when you turn it. The inside has a tiny engraving: 'A.H.' and a small heart symbol, plus a faint scratch along the inner edge from wear. It held a lot of sentimental value—it was my grandmother's ring and means the world to me. If anyone found it, please reach out; I’d be forever grateful to get it back.
