You can find the answer to this question when you discover the answer to the other rhetorical questions, such as why is air clear and why is rain wet?
Directly, because no other natural mineral has yet been discovered that is harder than diamond.
Fact
yes.
diamond
Yes it is. They are essentially compressed carbon; when the carbon is at a very high temperature and under very high pressure, the bonds are formed. Natural diamonds are made 180km below the earth’s surface. The temperatures at this depth are between 1100o c and 1400o c. Diamonds rank 10 (the highest) on the Mohs scale, range from transparent to opaque and is not affected by any chemicals.
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
Diamonds.
Fact
Diamonds are the hardest known substance
This is a fact. It can be verified by way of experimentation, and is true regardless of what anyone believes or disbelieves.
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.)
no diamonds are
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!
Diamonds are the hardest mineral on earth.
Diamond is the hardest known substance.
Same as others-just improved longevity since diamonds are hardest substance on Earth.
yes.
Diamond is the hardest natural mineral and about 80% of all diamonds mined are used by industry to enhance sharpness, focus and usefulness of tools. The remaining 20% are used as gem stones.
