Delicate 14k white-gold sapphire ring, Bath

I lost my delicate 14k white-gold ring yesterday around 3pm. It features a tiny blue sapphire bezel-set in the center and a subtle Celtic knot engraving on the inside of the band. I was walking along Pulteney Bridge toward North Parade by Bath Abbey when I must have dropped it on the pavement. The ring is in good condition aside from a small scratch on the outside, but the engraving makes it easy to identify. It was a gift from my grandmother and carries a lot of sentimental value—really hoping someone who finds it can return it.
