What is the harder rock, diamond or granite? - Quora

The stone hardness scale (Mohs scale) uses talc for the softest (1) example and diamond as the hardest(10) example. Most granite falls between 6 and 8, on this scale. You use diamonds to “cut" granite. Technically, diamonds are harder than granite. That is my understanding.
