Diamond is the hardest naturally occurring substance on Earth.
Aggregated Diamond Nanorod are the hardest overall and un-naturally occuring substance on Earth. They are actually a group of tiny diamonds which are virtually un-compressable.
Hope this helped!
The hardest naturally occurring substance after diamond is lonsdaleite, also known as hexagonal diamond. It is a rare form of carbon with a hexagonal crystal structure that is even harder than regular diamond due to its unique arrangement of atoms.
The hardest naturally occurring substance is diamond. Diamond is made of carbon atoms arranged in a strong crystal structure, making it extremely durable and resistant to scratching or breaking.
Diamonds are the HARDEST natural material. Mankind has created harder artificial materials.
There is nothing harder than Diamond. In answering this question, 'on earth' must be assumed, since there is no reference to 'naturally occurring in the universe' implied or contained within the question.
One of the hardest substances on earth, only a diamond is hard enough to cut other diamonds. It is possible only because the hardness of diamond varies widely according to the direction in which one is trying to cut or grind. Therefore a harder diamond is used to cut one that is slightly softer (due to impurities).
The hardest naturally occurring substance is called diamond. It is a form of carbon.
diamond is the hardest and graphite is the softest

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 mineral that has a hardness of 10 on the Mohs scale. It is the hardest naturally occurring substance.
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.
A diamond
Diamonds is not a stone it's crystal actually. But the hardest stone is granite stone.
Diamonds are the hardest known naturally occurring substance. Most diamonds are electrical insulators.
