Gold-tone leaf pendant necklace with ruby

Lost my gold-tone leaf pendant necklace yesterday around 3pm near the Brownsville Main Street Library plaza. It's an 18-inch chain with a leaf-shaped pendant and a tiny ruby in the center. The back is engraved with an 'M' and the clasp is stamped 925, a bit tarnished from wear. This necklace has sentimental value—it was a gift from my grandmother who passed away last year. If anyone found it, please reach out; I’d really appreciate getting it back.
