Lost sentimental gold chain necklace with delicate heart pendant in Meadowbrook Park, Champaign Urbana.

I lost a sentimental gold chain necklace with a delicate heart pendant while walking in Meadowbrook Park in Champaign Urbana last Sunday. It was a gift from my grandmother, and I'm really hoping someone might have found it and can return it to me. I remember taking it off for a moment to adjust my sweater and realized it was gone shortly after. I'd appreciate any help!
