Lost gold chain necklace with a tiny heart pendant near the playground bench in Memorial Park, Joplin.

I lost my gold chain necklace with a tiny heart pendant while walking in Memorial Park area in Joplin. I last remember having it when I was sitting on a bench near the playground, but I realized it was missing just after I got home. It's quite sentimental to me, as I received it as a gift from my grandmother. Please let me know if you find it!
