1 Diamond is an excellent electrical insulator, Graphite is a good conductor of electricity. 2  Diamond is the ultimate abrasive, Graphite is a very good lubricant. 3  Diamond is usually transparent, Graphite is opaque.  Diamond crystallizes in the Isometric system and graphite crystallizes in the hexagonal system.
