the diamond is very hard because it has crystallized at depth of 140-150 km( sometime it has crystallized at 300-400 km) into the earth to high pressure ranging approcimately betwen 45-60 kilobars and low temperature ranging approximately betwen 1652-2372 F(900-1300 C).
AnswerIts hard because it consists of very small atoms (carbon) that are then tightly packed together and linked via covalent bonds (bonds where two atoms share an electron). It is the combination of very tight packing and very tight linking that results in diamond being so hard.

How to make graphite hard?
To make graphite hard, it needs to be transformed into diamond through a process called diamond synthesis. This typically involves subjecting graphite to high pressures and temperatures in a controlled environment to rearrange its atomic structure into the tightly packed, rigid lattice of diamond.
The nitride of this element can be as hard as diamond?
The element is boron. Boron nitride exists in two forms, hexagonal and cubic, with the cubic form being as hard as diamond due to its strong covalent bonds. It is often used in high-temperature and high-friction applications as a lubricant or abrasive.
