How about a soapstone carving kit? You could include a selection of different types of soapstone, chiseling tools, rasps and sandpapers, as well as a booklet or DVD to give her ideas and instruction. Another idea could be to find a local artist who specializes in soapstone carving, and arrange a session for her to learn and gather tips. If your girlfriend specifically likes animals, look for a soapstone carving of her favorite animal, or if she likes abstract shapes, find a unique and modern piece to add to her collection.
Or you can get her a star map with the date of your first kiss.
