How about a personalized display case for her favorite fossils? You could also look for rare or unique fossils that she doesn't already have in her collection. Another idea could be a fossil hunting trip or a visit to a natural history museum where she can see even more fossils up-close. If your budget allows for it, you could also consider booking a private fossil collecting tour led by experts who can help her find some new specimens to add to her collection.
Or you can get her a star map with the date when she was born.
