18k gold ring with emerald, initials AJ

I lost my 18k gold ring with emerald inlay yesterday around 3pm. I was walking along King Street near the Castillo de San Marcos when it slipped off my finger and rolled into the dirt by the old City Gate. The ring is a slim, polished band about size 6.5, with a small emerald centerpiece and an inside engraving of the initials AJ. It's sentimental—it was a gift from my grandmother and means a lot to me, so I'd really appreciate finding it. If you happened to pick it up or see it, a quick text would help me a lot.
