How about a set of high-quality acrylic paints and a canvas so she can create her own abstract painting? You could also include a book on famous abstract painters or take her to a local art museum to see some abstract paintings in person. Another idea is to find an abstract painting workshop or class that she could attend to further develop her skills and make new friends who share her passion for art.
Or you can get her a star map with an important date you share.
