One idea could be to get her a subscription to a historical magazine or book club that focuses on the royal family or British history. Another idea could be to get her a collector's edition of The Crown on DVD or Blu-ray with behind-the-scenes footage and special features. You could also get her a historical fiction book set in a similar time period, such as The Windsor Knot by S.J. Bennett, which is a murder mystery set in the world of the royals. Finally, you could make her a custom necklace or bracelet with a crown charm, so she can wear her love for The Crown on her sleeve.
Or you can get her a star map with the date when she was born.
