Diamond
The softest known mineral is 'TALC'. The hardest known mineral is 'DIAMOND' (according to Friedrich Mohs scale)
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
The softest mineral is talc, and the hardest is diamond. You can check this on the Mohs hardness scale.
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.
Diamond is the hardest mineral mined in the north of Western Australia. It has a hardness of 10 on the Mohs scale, making it the hardest natural material known to man.
Diamond is the hardest mineral currently known and is an allotrope of carbon.
The hardest mineral is diamond, and the softest mineral is talc.
Diamond is the hardest mineral known.
Diamonds are the HARDEST natural material. Mankind has created harder artificial materials.
Diamonds are the hardest known substance
The hardest substance that is naturally occurring is a diamond. However, there are harder substances that have been made by scientists in labs.
Diamonds are the hardest known mineral or stone found in nature. It is rated a 10 on the hardness scale known as the Mohs Scale.
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.)
Diamond is the hardest known natural substance, with a score of 10 on the Mohs scale of mineral hardness. It is made up of carbon atoms arranged in a crystal lattice structure, giving it its exceptional hardness and durability.
The hardness of diamond is a physical property of the diamond. The statement is also untrue as diamond is only the hardest known mineral, not the hardest known substance.
Diamond is the mineral that is most resistant to being scratched. It is the hardest known natural substance, scoring a 10 on the Mohs scale of mineral hardness.
Original answer: yes-it is the strongest substance on earthYes, diamond is the strongest Natural substance on earth, but it is not nearly the strongest substance of all, and diamond is a mineral... not a metal... there are other ores such as titanium and tungsten that can be strengthened to become thousands of times stronger than diamond.
