Graphite is a form of carbon. It has the same chemical composition as diamond, but the arrangement of its atoms, in loosely-bonded layers, gives it very different properties. Graphite is very soft, and leaves a mark on paper, whereas diamond is extremely hard.

Graphite is most commonly found in metamorphic rocks which have been altered under under conditions of high temperature, and much of it derives from carbonaceous material of sedimentary origin.

Graphite is used as the "lead" in pencils.
