How about a custom-made necklace or bracelet with a scuba diving charm? You can choose the type of metal and customize the length to her preference. Another idea could be to gift her a scuba diving experience or certification course if she hasn't already done so. If she already has the certification, you could gift her a scuba diving trip to a destination of her choice or a book on scuba diving featuring amazing dive spots.
Or you can get her a star map with the date when she was born.
