One idea could be a book that explores different societies and cultures through ethnographic studies. You can look for popular books in this genre such as "The Spirit Catches You and You Fall Down" by Anne Fadiman, "Deer Hunting with Jesus" by Joe Bageant, "Emotional Agility" by Susan David or "The Hidden Life of Trees" by Peter Wohlleben.
Another idea could be a subscription to a magazine or journal that specializes in anthropology or ethnography, such as "American Anthropologist" or "Ethnography".
You could also consider arranging for her to attend an ethnographic conference or workshop in her field of interest. Many academic institutions offer these types of events and would be a unique opportunity for her to connect with other like-minded individuals and learn from experts in her field.
Finally, you could consider purchasing her some ethnographic artifacts, such as handmade pottery or textiles from a variety of cultures around the world, or an art piece that depicts a cultural or spiritual tradition. You could also consider arranging for her to visit a museum exhibit focused on ethnography or cultural studies.
Or you can get her a star map with an important date you share.
