A scuba diving experience would make a lovely and thoughtful wedding gift for your friend who enjoys scuba diving. You could buy him/her a gift certificate for a scuba diving lesson or a guided scuba diving tour. There are many resorts and companies that offer great and fun scuba diving experiences around the world. Another great idea could be buying an underwater camera or an action camera that they can use when scuba diving. This would allow them to capture and document their scuba diving adventures and memories.
Or you can get her/him a star map with the date of the wedding.
