One idea could be to get her a high-quality fountain pen in a unique and personalized design. Some brands like Parker or Lamy offer customizable pens with different engraving or color options. Another possibility could be to get her a fountain pen set that includes different nibs, inks, and paper to experiment with. You could also consider a handmade leather pen case or a book on the history and art of fountain pens to complement the gift. Lastly, you could arrange a visit to a local fountain pen shop or attend a calligraphy workshop together to share your mutual interest in the subject.
Or you can get her a star map with an important date you share.
