Diamonds are considered to b the hardest substance on earth,diamonds r brilliant & bright. The speed of light in a vacuum is 186,000miles per second but light slows down a little wen passing through a matter.Diamonds also bends and reflect light and break it up into the colours of the rainbow,which is what gives them their sparkle!

because of very strong sigma bond between each carbon atom

As we know that carbon is the most powerful element. Study of only carbon atom will takes years because the only element will form chemistry of organic called "organic chemistry. In diomand there are strond unbreakable covalent bonds exists so it is very harder in nature.

Due strong bonding 8 e held tightly so thats why.

Because of strong covalent bond between the carbon atom.

In diomond there are covalent bonds between carbon-carbon atoms and these bonds are very strong and almost impossible to break.

There are strong chemical bonding b/w their chemicals and its unbreakable due to this its a strong among them.

All metals are hard, and so all not metals are soft - obviously the characteristics of all metals and non metals are opposite to each other. Since diamond is hard, we cannot say that it is a metal. It is an exceptional case in non metals. Diamond is a hard " non - metal ".

Because of sp3 hybradisation with bond length 1.42a.
That's why it is strongest metal.
That's why it is strongest metal.

It is so hard that only a other diamond can cut the original diamond ! lesson to learn is: share mutually like carbon atoms in the diamond and lead a rigid life.
