Silver ring with emerald, lost near Coligny Plaza

I lost my silver ring yesterday around 3pm near the Coligny Plaza fountain on Pope Avenue in Hilton Head. It's a slim silver band, size 6.5, with a tiny emerald about 4mm across, and there’s a delicate engraving on the inside—'AJ'—plus a barely visible scratch at the 2 o'clock position. This ring was a gift from my grandmother, and it means a lot to me; I wear it every day and I’m really hoping to get it back. If you found it, please drop it at the Coligny Plaza security desk and I’ll pick it up there—so grateful for any help.
