A great gift idea for your mom who likes geology would be a beautiful rock or mineral specimen to add to her collection. You could also consider getting her a book about geology or even a guided geological tour of a nearby area. Another great option would be to get her a stylish piece of jewelry that features her favorite rock or mineral. Lastly, you could consider subscribing her to a geology magazine or signing her up for a geology class or workshop.
Or you can get her a star map with the date when she gave birth to you.
