A great gift for a grandma who loves rocks and minerals could be a personalized rock or mineral kit. You could get her a set of geodes or polished stones, and add a note explaining the type of rock or mineral and where it was found. Some other gift ideas could be:
1. A book about rocks and minerals for her to learn more about her collection.
2. A subscription to a rock and mineral magazine.
3. A personalized rock tumbler kit so she can polish her own rocks at home.
4. A piece of jewelry made with her favorite gemstone or crystal.
5. A framed print of a beautiful geological formation or scenery.
6. A gift certificate to a nearby rock and mineral store or museum.
Or you can get her a star map with an important date you share.
