Each carbon atom in the crystalline lattice of a diamond is sp3 hybridised.
The length of the C-C covalent bond between each carbon atom and the other four carbon atoms is 154 pm.
A rigid 3-D network of carbon atoms with directional covalent bonds results from the structure’s extension into space.
Diamond is the earth’s hardest material because extended covalent bonding is very difficult to break.
