Gold pendant necklace with pearl centerpiece

I lost my gold pendant necklace yesterday around 3pm near the Utica Public Library on Genesee Street. It’s a slim 18-inch, 14k gold-plated chain with a small heart pendant containing a freshwater pearl, and the back is scratched with a tiny 'A'. The clasp sometimes sticks, which makes it easy to miss. I treasure it because it was a gift from my grandmother and it has sentimental value. If anyone found it, I’d really appreciate getting it back.
