How about giving her a soap making kit or a gift card to a soap making class? Alternatively, you could put together a basket of different soap making ingredients for her to experiment with, like essential oils, natural colorants, and different types of oils and butters. If she's interested in the science behind soap making, there are some great books on the subject that you could gift her as well. Another idea is to give her a personalized soap bar with her favorite fragrance and design.
Or you can get her a star map with the date of your first kiss.
