How about getting her a subscription to an art magazine, like Frieze or Artforum? This way she can stay up-to-date on the latest happenings in the contemporary art world. Another idea could be purchasing a piece of abstract art for her to display in her room or apartment. You could also get her a book on a specific contemporary artist she admires or a coffee table book showcasing modern art movements. If you want something more experiential, you might consider taking her to an exhibit or event featuring contemporary art that she is interested in.
Or you can get her a star map with an important date you share.
