How about tickets to a cultural dance performance? You can do some research and find out when and where a local cultural dance group is performing. That would be a very meaningful and personal gift for your girlfriend. Additionally, you can make a whole romantic evening out of it by booking a nice dinner reservation after the performance.
Or you can get her a star map with the date of your first kiss.
