The Mohls scale goes from 1-10,with 10 being the hardest. Diamonds are the hardest natural stone with a rating of 10.

Diamond is the hardest mineral on earth and in jewelry. Using the Mohs scale of mineral hardness, 1-10 one being softest, diamonds rank a ten. Diamonds are so hard because of their crystal lattice that hold them together by covalent bonds, not ionic bonds. Ionic bonds are what hold salt crystals together.

Diamonds as far as I know. I heard diamonds themselves actually need to be cut with other diamonds. (Whatever tools they use, they have to be diamond tipped. ) Given I'm wondering: if that's the case, how are the tool tips made/shaped?
