How about a personalized rock that she can use as a paperweight or display on her desk? You can purchase a smooth rock and either paint or write a message on it, such as "world's best grandma" or her favorite rock lyric. Additionally, you could get her a CD or vinyl record of her favorite rock band or artist, or concert tickets to see a rock concert she might enjoy. If she's a reader, you could get her a book about her favorite rock band or musician. Finally, you could consider getting her a piece of jewelry with a rock motif, like a necklace or bracelet made out of her favorite stones.
Or you can get her a star map with an important date you share.
