Five Star Gift Ideas

How about a calligraphy set? I'd recommend the Tombow Beginner Lettering Set, which comes with a dual brush pen, a Fudenosuke pen, a MONO Twin permanent marker, and an eraser. You could also get her a book on calligraphy, like "The Calligrapher's Bible" by David Harris, or a set of personalized stationery so she can practice her craft. Another idea would be a calligraphy class or workshop in your area. This would give her an opportunity to learn from experts and network with other calligraphers.

Or you can get her a star map with the date of your first kiss.

David Dickason says about Under Lucky Stars star maps:

“Ordered a map of the stars above us when my wife and I realized that we wanted a friendship to turn into something more - gave it to her yesterday (Valentine's Day) and got a most enthusiastic response. We are best pleased!”
