Lost gold locket with delicate floral design containing a grandmother's picture, lost in Ames Park, Ames, IA.

I lost a beautiful gold locket with a delicate floral design while walking my dog in the Ames park last Sunday afternoon. It's quite special to me as it contains a picture of my grandmother inside. It must have slipped off my neck during our walk. If anyone finds it, I would be immensely grateful!
