Diamond.
Diamond is still the hardest substance known to man. Various carbides such as tungsten carbide, boron carbide, and silicon carbide are also extremely hard, but you will notice that they all contain carbon (diamond is pure carbon - the rest are carbon compounds.)
No. Diamond is a hard mineral, the hardest natural mineral on earth.
The hardest substance that is naturally occurring is a diamond. However, there are harder substances that have been made by scientists in labs.
Diamond is the hardest natural substance on Earth, ranking 10 on the Mohs scale of mineral hardness, due to its tightly packed carbon atoms in a strong crystal lattice structure.
Diamond, the compressed form of carbon.
Diamond is the hardest mineral currently known and is an allotrope of carbon.
It is the hardest NATURAL substance- due to the arrangement of the carbon atoms that make up a diamond. (Thee ARE harder materials, but they are manmade.)

The hardest naturally occurring substance is called diamond. It is a form of carbon.
Diamond is the hardest natural substance on Earth, ranking 10 on the Mohs scale of mineral hardness, due to its tightly packed carbon atoms in a strong crystal lattice structure.
Diamond is the hardest mineral in the group, ranking 10 on the Mohs hardness scale. It is composed of carbon atoms arranged in a crystal lattice structure, giving it exceptional hardness and durability.
Man-made diamonds are not considered natural because, by definition, a mineral must form by natural processes.
No, Diamond which is entirely made up of carbon is the hardest
No, diamond is not a soft crystalline form of carbon. It is the hardest naturally occurring substance on Earth. Diamond's hardness is a result of its unique crystal structure and strong bonds between carbon atoms.
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
