    Diamond and graphite are both the compounds of carbon......they differ in their structure.... In diamond all the e- of carbon are engaged in their bonds but in graphite one of pair of e- is left unpaired ....... That is why graphite appears black where as diamond is crystal clear ..... The reason is for the rigidity of diamond and the brittleness of graphite
