How about getting your grandma a fossil hunting field kit? You could include a sturdy canvas field bag, a magnifying glass, a rock hammer, fossil identification guide, and a set of chisels and brushes for getting the fossils out of the rock. You could also add a personalized note to the kit, letting her know how much you appreciate her love and support. Another idea is to take her on a fossil hunting trip with a local guide, or to a museum to see some amazing fossil exhibits.
Or you can get her a star map with the date when she was born.
