The hardest naturally occurring substance is called diamond. It is a form of carbon.
Diamond
Diamond use to be the hardest known natural substance now it is the mineral lonsdaleite at 58% stronger then diamond is the first the second hardest is wurtzite boron nitride at 18% stronger then diamonds they are both extreamly rare natural minerals sources http://www.newscientist.com/article/dn16610-diamond-no-longer-natures-hardest-material.html
diamond is the hardest and graphite is the softest
That statement is a fact. Diamonds are indeed the hardest naturally occurring substance on Earth, as they score a 10 on the Mohs scale of mineral hardness.
The hardest substance in the teeth is the enamel, which is the outer layer that protects the teeth from wear and decay. Enamel is primarily made up of minerals like hydroxyapatite, making it extremely strong and durable. However, enamel can still be damaged by acids and physical trauma.

Yes.
diamond is the hardest and graphite is the softest
Diamond is the hardest substance in the world, but the second hardest substance is boron nitride. It is often used in high-temperature and high-friction applications due to its exceptional hardness and thermal stability.
