How about getting him a piece of traditional Tibetan artwork, like a thangka painting or a Tibetan singing bowl? You could also consider a book on Tibetan culture or a traditional Tibetan clothing item like a chuba or a pair of handmade Tibetan boots. If he enjoys tea, you could also buy him some authentic Tibetan tea and a traditional tea set to serve it in. Another option could be a trip to a local Tibetan cultural center or museum to learn more about the culture together.
Or you can get him a star map with the date of your anniversary.
