Here is an explanation:

Carbon have two major allotrope which are Diamond and graphite. diamond is very hard to be drawn into pencils and its octahedral structure is not supportive; only graphite have the suitable characteristics to be drawn in to pencils with other materials because it is soft by its hexagonal crystal lattice structure in nature.
