Diamond
The formation of the diamond molecule and microscopic properties
Diamond is an allotrope of carbon,
It's in an extremely stable giant covalent lattice . However an other allotrope of carbon is graphite. Its not as hard as diamond as it has a different covalent structure.
Its tetrahydrally bonded which means that it forms a sort of triangle lattice. This almost perfect structure gives the formation below.
Arranged in a honeycomb
lattice in parallel layers

Van der Waals forces
Strong covalent bonds

Carbon Nanotube
Carbon nanotube is an allotropes of carbon with a cylindrical nanostructure. Carbon nanotube is a great conductor of heat and is used in different electronics. Carbon nanotube is part of the fullerine structural family and and is usually in a liquid form or in one atom thick sheets.
