How about a fossil kit? You can buy her a kit that includes real fossils and tools for digging and cleaning them. You can also consider getting her a subscription to a monthly fossil club where she can receive new fossils every month. If she likes jewelry, you can also find fossil necklaces or earrings that would make a unique and meaningful gift. Another idea is to take her on a fossil hunting excursion or visit a natural history museum that has a special exhibit on fossils.
Or you can get her a star map with the date when she was born.
