For me, it is a bit late for you to ask this question bro. For a present in a week, you can only buy some nice present. Look at her, what things that she does not have?

For example : necklace, bracelet. These can be your gifts to her.

If not, you can treat her for a good dinner around that area. just google. Will be good if you can complete the dinner with a good choice of wine.

Just my 2 cents
