How about a personalized chess set with their wedding date and initials engraved? You could also include a beautiful wooden chess board or case for the pieces. Another idea could be a chess clock to help them time their moves during games. If they already have a nice set, consider getting them a chess-themed piece of art or a book about the history of chess. Alternatively, you could arrange for a private chess lesson with a local chess master as a fun and unique experience gift.
Or you can get her/him a star map with the date of the wedding.
