How about a personalized geode or mineral specimen? You could have a geode or rock cut open and then personalized with a special message or your girlfriend's name. Alternatively, you could purchase a beautiful crystal piece or some fossils encased in acrylic to display on a desk or shelf. Another option could be to book a geology-themed trip or tour to a national park, caves, or an area known for its geological wonders. You could also consider purchasing a book about geology or a subscription to a geology-related magazine.
Or you can get her a star map with the date of your first kiss.
