How about a handmade honeycomb necklace or honeycomb earrings? These could be made from brass or silver, and they'd make a unique addition to his beekeeping outfit. If he has a garden, you could also gift him a bee-friendly plant or even a bee hotel. Another option would be a custom-made beehive kit or a subscription to a beekeeping magazine or club. These gifts would show him that you support his hobby and that you've put thought into what he loves.
Or you can get him a star map with the date of your anniversary.
