Diamonds are the hardest known naturally formed rock on earth. Both Mohs’ scale and Vickers scale determined diamond as the hardest rock on earth. It is considered the hardest mineral because it is most difficult to cut or break.
Diamond is said to have originated around 2500BC. It is believed that diamond got its name from the Greek word “Adamas,” meaning “unbreakable” or “unconquerable.” There are several mythological stories associated with diamonds’ origin, but people commonly believed that diamonds were something outside of the world.

Diamond is regarded as the hardest rock in the world, and it tops 10 on the Mohs scale. Diamond is so hard that it can cut anything. Nothing can cut or break diamonds but themselves.

A Decade back, scientists discovered two harder materials than diamond- wurtzite boron nitride and the mineral lonsdaleite. Both have a similar structure to diamond but consist of different atoms.
