How about a set of antique jewelry or a vintage perfume bottle or a vintage tea set? You could also consider getting her an antique book or a vintage record player with some old records. If you're looking for something a bit more personalized, you could find an antique trinket box, fill it with some of her favorite things, and then personalize it with her name. Another idea is to take her on a vintage shopping spree where you both can hunt for unique antiques together or you could even take her to a local antique festival, where she can find some unique and one-of-a-kind pieces to add to her collection.
Or you can get her a star map with an important date you share.
