Gold-tone heart pendant necklace

I lost my gold-tone necklace yesterday around 3pm near the Sample Gates on Kirkwood Ave in Bloomington. It's a 16-inch chain with a tiny heart pendant. The pendant has a little engraving on the back—'A.P.'—and there's a small telltale scratch near the clasp from daily wear. It was a gift from my grandmother and has huge sentimental value; I really need it back. If anyone found it, please email me at [email protected].
