How about a beautiful Tarot deck and a book that goes into the history and meaning of tarot cards? This way, he can learn more about the meanings behind the cards and use them for his personal practice. You could also get him a special tarot reading with a trusted tarot reader, or even organize for him to take a tarot workshop or class to learn more about the art of tarot reading. Another idea is a figurine or a framed art piece featuring a tarot card he likes, something he can have on display in his workspace or on a shelf at home.
Or you can get him a star map with the date of your anniversary.
