How about a personalized coffee mug that says "World's Best Grandma" or something similar? You could also find a unique and interesting coffee mug that fits her personality, such as one with her favorite animal or flower on it. Another idea could be to get her a subscription to a monthly coffee mug club that sends her a new mug each month. This way, she can add to her collection and have a variety of new mugs to display or use.
Or you can get her a star map with the date when she was born.
