Gold-tone necklace with compass pendant

I lost my gold-tone necklace with a tiny compass pendant yesterday around 3pm near the CVS on Main Street, just outside the Yuma Public Library. It's an 18-inch chain with a small, slightly aged gold finish and a compass pendant about the size of a nickel. The back is engraved with the initials 'PP' and there’s a tiny blue stone at the center of the compass. It has sentimental value—it was a gift from my late grandmother, so I’ve been worried and really hope someone picked it up. If you’ve seen it, I’d be grateful to reunite it with me.
