14k gold heart pendant necklace with ruby

I lost my 14k gold heart pendant necklace yesterday around 3pm near the Bob Kerrey Pedestrian Bridge along the riverfront in downtown Omaha, right near the Omaha/Council Bluffs border. It's a delicate 16-inch chain with a tiny heart pendant that holds a small ruby in the center. The back is engraved with the letter 'A', and the clasp is a bit bent from wear. This necklace means a lot to me—it's a gift from my grandmother and carries a lot of sentimental value. If someone found it, please leave a note in the app and I will arrange a convenient meetup nearby.
