Lost silver bracelet with heart, star, and tiny book charms near a walking path in a park in Cambridge.

I lost my beloved silver bracelet while visiting my sister in a park near Cambridge, somewhere along the walking path. The bracelet has several charms that are meaningful to me, including a heart, a star, and a tiny book. I last remember having it on my wrist when we stopped for a picnic. If found, I would really appreciate its return.
