A great wedding gift for your friend who likes Tibetan culture could be a set of traditional Tibetan prayer flags or a Tibetan singing bowl that they can use for meditation or relaxation. You could also consider gifting them a beautiful traditional Tibetan thangka painting, which is a intricate piece of art that is often used as a form of meditation. Another great option could be a book on Tibetan cuisine, as your friend might enjoy exploring the unique flavors and combinations of the culture's dishes.
Or you can get her/him a star map with the date of the wedding.
