Lost gold signet ring with engraved initials

I lost my gold signet ring yesterday around 3pm near Exeter Cathedral on High Street. It's a 14k gold signet with a slightly worn band, about the width of a fingernail, and a tiny blue enamel crescent on the outside. Inside the band is engraved 'A.P.' and there’s a faint scratch along the back from wear. It’s really sentimental to me because it was a gift from my grandmother, and I’m worried I’ll never get it back if it doesn’t show up soon. If you found it, message me — I’d be so grateful to get it back.
