How about an original piece of contemporary art as a wedding gift? You can find unique and meaningful pieces that your friend will appreciate for years to come, and that will remind them of their special day. If you know of any local galleries or art fairs that specialize in contemporary art, these would be great places to start. Alternatively, you could consider commissioning a local artist to create a custom piece that reflects your friend's style and taste. Another idea could be a coffee table book featuring the works of contemporary artists your friend admires.
Or you can get her/him a star map with the date of the wedding.
