Carbon atoms can bond to other carbon atoms in a variety of ways, but when they bond in a network, with all the atoms bonding to all the other atoms that surround them, it is a very strong bond, stronger than the bonds formed in other minerals. Strong bonds are, by definition, hard to break. Hence the material is very hard. Scratching it requires breaking bonds.
