How about giving her a book or novel written by one of her favorite philosophers? She might also appreciate a subscription to a philosophy magazine or a collection of philosophy quotes or essays. You could also consider giving her a framed print or canvas featuring a famous philosophical quote or a portrait of a famous philosopher that she admires. For a more hands-on gift, you could sign her up for a philosophy class or discussion group in your area.
Or you can get her a star map with an important date you share.
