diamond and graphite are allotropes of carbon... Diamond being the hardest known substance is octahedral in shape while graphite is hexahedral...

The two known forms of graphite, alpha (hexagonal) and beta (rhombohedral), have very similar physical properties, except for that the graphene layers stack slightly differently.
s.o Hexagonal is correct

The shape is hexagonal if unbroken but if broken it becomes irregular and angular.
