How about a vintage-inspired jewelry box? You can find many lovely options that are reminiscent of antique designs. You could also look for a vintage or antique piece of jewelry for her to add to her collection. Another idea could be a guided tour of a nearby antique store or antique fair, followed by a nice lunch or dinner with her. If you want to get something more practical, you could consider a subscription to a magazine or newsletter focused on antiques, or a new set of antique-inspired tableware or decor.
Or you can get her a star map with the date when she gave birth to you.
