The molecular structure is different. Carbon atoms in graphite are bonded in layers with only weak covalent bonds holding the layers together. When you write with a pencil some of the layers detach from the pencil lead and attach to the paper. Carbon atoms in diamond are bonded in a stronger tetrahedron pattern.
