How about a personalized leather journal embossed with a horse design or his initials? He can use it to jot down notes while attending equestrian events or just to keep track of his thoughts and ideas. Alternatively, you could gift him a customized horse-themed photo album where he can showcase his favorite equestrian memories. You could also consider a good coffee table book such as Spirit of the Horse, The New Encyclopedia of the Horse, or The Horse: The Epic History of Our Noble Companion. Additionally, you could gift him a piece of equestrian-themed jewelry such as a horsehead pendant or cufflinks.
Or you can get him a star map with an important date you share.
