Gold signet ring with emerald accent, sentimental value

I lost my gold signet ring with an emerald setting yesterday around 3pm near Market Street outside the Arndale Centre in Manchester city centre. The ring is about 7mm wide, 14k gold-plated, with a small square-cut emerald. It has a couple of light scratches along the band from years of wear. Inside the band, there's a discreet engraving 'LA' and a tiny date '21/04' that's barely visible. It was a gift from my grandmother and means a lot to me—really hoping someone picked it up.
