Introduction. An integral tool from the time we’re toddlers, graphite is most known as the active ingredient in lead pencils. It is one of the three familiar naturally occurring forms of the chemical element carbon, along with amorphous carbon (not to be confused with amorphous graphite) and diamond.

Crystals are commonly recognized, macroscopically, by their shape, consisting of flat faces with sharp angles. These shape characteristics are not necessary for a crystal—a crystal is scientifically defined by its microscopic atomic arrangement, not its macroscopic shape—but the characteristic macroscopic shape is often present and easy to see.
