I suggest getting her the official companion book to The Crown. This book provides behind-the-scenes insights into the show, including interviews with the cast and crew, detailed set and costume designs, and never-before-seen photographs. Additionally, you could include a set of tea cups and a tea kettle so she can enjoy a cup of tea while she dives into the book. This would be a thoughtful gift for any fan of the show, and show that you have been paying attention to her interests!
Or you can get her a star map with an important date you share.
