How about a ballet-inspired necklace or bracelet? You can find ones with charms in the shape of ballet shoes or tutus. Alternatively, you could get her a ticket to see a ballet performance, take her out to a nice dinner before or after, and make it a special day for her. Another idea could be a coffee table book on ballet with stunning photographs and history of the art form.
Or you can get her a star map with the date when she was born.
