I’m looking for a picture book that is possibly German, maybe Swedish or maybe something else. It is illustrated in a very rough ripped paper collage. There is a little girl who is making a necklace; I think she is naked or  barely clothed. She has red hair. At one point she goes into a cave with gems and gets a gem for her necklace. I never actually read the words as I don’t speak whatever language it was in. She may have also gotten a shell for her necklace but I’m less sure of that. Thanks so much for any help.
