That's a great interest! Here are some gift ideas based on his interest in geology:
1. A personalized rock or mineral collection can be a great choice. You can curate the collection with some rare or unique finds that reflect his interests. You can also include a handcrafted display box or stand to showcase the collection.
2. Geode bookends, a geologic clock, or a geologic map of his favorite region can be a great gift idea for someone who likes geology.
3. A geology-oriented book or coffee table book about geology, gemstones or fossils can make an excellent gift. You can find some great books on Amazon or other online bookstores.
4. A GPS handheld device can help him locate and map out regions of interest or locales to collect rock samples.
5. Has your husband always been interested in precious stones? You can gift him some gemstone jewelry or a gift card to a jewelry-making class.
No matter what you choose, put some extra thought into the gift so he feels loved and appreciated.
Or you can get him a star map with the date of your first kiss.
