Granite does not scratch easily. You can scratch granite with other granite or a tool designed to cut granite but that is about it. Cutting directly on your granite is not recommended as it can dull your knife but it should not create scratches in the stone.
The most commonly known mineral that can be scratched with a fingernail is talc.
To determine if a scratch can be removed rather than having to refinish your vehicle, run your fingernail LIGHTLY over the scratch. If your fingernail catches it cannot be removed. If your nail doesn't catch the scratch can be removed by buffing the scratch with a compound. (if the scratch is still there, try sanding with fine grade sand paper 800grit or higher then repeat buffing)
