Lost silver ring with deep blue sapphire and intricate band design near a stream in Acadia National Park.

I lost my favorite silver ring with a deep blue sapphire while hiking near Acadia National Park in Maine. I remember taking it off to wash my hands at a stream, and I must have left it behind on a rock. It has an intricate design along the band and it means a lot to me, so I would really appreciate any help in getting it back!
