The difference is based on differnces in atomic lattice.
Graphite is soft, black, and greasy to the touch. It is made up of carbon atoms arranged in an extended lattice of hexagonal plates. Layers of plates slip easily against one another.
Diamond is hard, clear, and crystalline. Carbon atoms are arranged in a tetrahedral lattice that is extremely rigid.

The difference lies in the arrangement of the atoms.
In graphite the atoms are arranged mainly in parallel sheets, which have "loose" ties to the sheets on either side. The sheets can move relative to each other, making graphite somewhat weak.
In diamond, a different atom structure is in place. The atoms are far more rigidly bound in this structure, giving diamond its unique hardness.

the network covalent structure differs. this means that even though they are both made of carbon, the way in which the carbons are arranged differ. The graphite is arranged in a way that makes it susceptible to break in sheets while the graphite is configured in a way that makes it difficult to split or break apart in nearly all situations

the pattern of the lattice in diamond is stronger than that in graphite. Actually, when arranged properly, graphite (carbon composite actually) is stronger than steel.
