How about getting her a personalized rock painting kit? The kit can include different sizes and shapes of rocks, paint markers, and stencils. You could also include a book or guide about identifying different types of rocks and minerals to make it even more meaningful. Additionally, a subscription to a monthly rock and mineral magazine or membership to a local rock collecting club would be a great addition to her collection.
Or you can get her a star map with the date when she was born.
