Sterling silver heart pendant with sapphire and initials

I lost my sterling silver heart pendant yesterday around 3pm near the Chautauqua Library by the Fountain on Oak Street. The pendant is about the size of a dime, on a thin 16-inch chain, with a tiny blue sapphire set in the center. On the back is a small engraving 'AJ' that’s easy to spot after wear. It means a lot to me—a gift from my grandmother—and I’m really hoping it turns up near the library or the fountain area. If you found it, please reach out; I’d be so grateful to get it back.
