What is the 2nd hardest material on earth?

Boron nitride

c-BN is chemically and thermally stable, and is commonly used today as a superhard machine tool coating in the automotive and aerospace industries. But cubic boron nitride is still, at best, just the world's second hardest material with a Vickers hardness of around 50 GPa.

Why diamond is the hardest mineral?

The outermost shell of each carbon atom has four electrons. In diamond, these electrons are shared with four other carbon atoms to form very strong chemical bonds resulting in an extremely rigid tetrahedral crystal. It is this simple, tightly-bonded arrangement that makes diamond one of the hardest substances on Earth.
