Gold-tone necklace with heart pendant

Hey there, I lost my gold-tone necklace with a tiny heart pendant yesterday around 3pm near Thornes Market on Main Street in Northampton. The chain is about 18 inches, slightly worn, and the heart charm has my initials 'P.P.' engraved on the back. There’s a small sapphire bead near the clasp that’s easy to spot if you know what you’re looking for. This necklace means a lot to me—it was a gift from my grandmother, and I’m really hoping it turns up soon.
