Sterling silver necklace with heart pendant engraved A.J.

I lost my sterling silver necklace yesterday around 3pm near the Lima Mall on Elida Road, outside the food court. It’s an 18-inch handmade chain with a small heart pendant, about 1/2 inch tall, featuring two tiny marcasite stones along the edge and an 'A.J.' engraving on the back. There’s also a tiny leaf charm near the clasp. It’s meaningful to me because it was a gift from my grandmother who passed away last year, and I wear it every day. If anyone found it, I’d be incredibly grateful to get it back.
