Silver pendant necklace with heart charm

I’m hoping someone picked up my silver pendant necklace yesterday around 3pm near the Amarillo Civic Center Plaza. It’s a slender sterling-silver chain, about 16 inches, with a tiny heart charm and a small initial A engraved on the back. The clasp is a standard spring ring, and the chain shows a bit of tarnish from wear, but it’s otherwise in good condition. It was a gift from my sister and carries a lot of sentimental value; I really need it back. If you found it, please text me and I can meet up near the Civic Center or Buchanan Street to pick it up.
