A great gift idea could be a vintage jewelry box to display her collection in, or a personalized engraving of her initials on the box to make it more special. You could also look for a unique vintage piece to add to her collection, such as a vintage brooch or necklace that you know she doesn't already have. Another idea could be to book a guided tour of a vintage jewelry store or museum for her to go to and explore her passion.
Or you can get her a star map with an important date you share.
