Diamond and graphite are allotropes of carbon and have various differences in their physical properties.

Explanation:

Diamond:

It is crystalline in nature
Each Each C is $sp^{3}$ hybridized and forms 4 covalent binds with neighboring C atoms
The geometry is tetrahedral
C-C bond length is 154 pm
It has rigid covalent boning which is difficult to break.
It acts as an electric insulator

Graphite:

It has layered structure
Each C atom is sp2 hybridized and forms 3 sigma bonds with 3 other C atoms. Fourth electron forms pi bond.
The geometry is planar
C-C bond length is 141.5 pm
It is soft. Its layers can be separated easily
It is good conductor of electricity.

This is the comparison of the physical properties of two forms of carbon: diamond and graphite
