Silver-tone chain necklace with compass pendant

I was wearing a Fossil brand silver-tone chain necklace yesterday around 3pm when I realized it was gone. The chain is about 18 inches long, with a small compass pendant about the size of a dime; the back is engraved with my initials EM. The chain shows light wear, and there’s a tiny scratch on the compass glass, but overall it’s in decent condition. I think I dropped it near Riverfront Park along Front Street in Burlington, IA, close to the fountain by the benches. It has serious sentimental value—my grandfather gave it to me—and I’d really appreciate getting it back if someone finds it.
