Silver-toned necklace with heart pendant

I lost my silver-toned necklace yesterday around 3pm near the Prescott Courthouse Square, by Cortez Street and Whiskey Row. It's a slim 18-inch chain with a small heart pendant, about the size of a dime, and the clasp has a tiny bend that makes it a bit unique. On the back of the pendant there's initials 'LM' engraved, plus a tiny ruby bead set into the corner. It has sentimental value—it's a gift from my mom, and I'm really hoping someone picked it up. If you found it, please message me so we can arrange a meetup downtown; I can share more details to confirm it's mine.
