14k gold ring with sapphire center and initials

I'm hoping someone turned in a ring I lost yesterday around 3pm near the USS Lexington Museum on the Bay along Shoreline Boulevard by the water taxi dock. It's a slim 14k gold band, about size 7, with a tiny blue sapphire bezel-set on top and a small compass charm dangling from the side. Inside the band there's a discreet engraving: 'A.J.' It's sentimental - it was a gift from my late grandfather, and I'm really hoping to get it back.
