For your granddaughter who likes collecting rocks or minerals, you might consider a personalized rock collection box. This is a cool and unique way to house and display her collection in one special place. You could also look for a set of minerals or rocks that she doesn't have in her collection yet, paired with a book or guide explaining each specimen. Alternatively, a one-year subscription to a rock collecting magazine could be a great idea to keep her interest in this hobby alive throughout the year.
Or you can get her a star map with an important date you share.
