14k gold ring with sapphire, sentimental loss

I was walking along the Harbor Walk by the Corpus Christi Marina around 3pm yesterday when I must have dropped it. It's a 14k yellow gold ring, slim and simple—size 6 and about 2.2 mm wide—with a tiny sapphire bezel-set at the top and a brushed finish. Inside the band there's a small engraving 'M.F.' and you can see a couple of wear scratches from years of wear. It’s the ring my grandmother gave me, so it means the world to me and I really need it back. If you found it, please message me—any lead would help, and I’ll be forever grateful.
