Three forms (or 'allotropes') of pure carbon are diamond, graphite and buckminster fullerene (or 'buckyballs'). In all three allotropes the carbon atoms are joined by strong covalent bonds but in such different arrangements that the properties of the allotropes are very different.

Here is ur answer,
Allotropes are the elements present in same chemical form but various physical forms .
The allotropes of carbon are diamond and graphite.
Diamond is hard ,beautiful crystalline substance while graphite is a soft grayish black crystalline substance.
In diamond each carbon is linked to four other neighbouring carbon atoms held by corners of a regular tetrahedron by covalent bonds to form a rigid three dimensional structure. while in the case of graphite each carbon atom is linked to three other carbon atoms forming a hexagonal planar structure.
in diamond there are no mobile electrons in the system and hence Diamond crystal is a non conductor of electricity on the other hand in graphite free electrons move throughout the entire layers and hence graphite is a good conductor of electricity.
Hope it helps you !
