Silver heart pendant necklace with inscription

I lost my silver heart pendant necklace yesterday around 3pm near the Starbucks on Broad Street in Cartersville. It's a 18-inch sterling-silver chain with a small heart pendant; the back is engraved with the initials 'A.M.' and there's a tiny chip on the rim. The necklace is slightly tarnished from daily wear but in decent condition, and it has huge sentimental value—it was a gift from my mom. If anyone found it, I’d really appreciate getting it back.
