  • Think of it this way: The graphite in a pencil and a diamond differ only in how their carbon atoms are arranged.

    FORBES: Tiny Miracles

  • Elemental carbon had long been thought to exist in only three physical forms: graphite, diamond and an amorphous form, of which charcoal is an example.

    ECONOMIST: Space-age soot

  • Belonging to a class of worlds known as diamond planets, 55 Cancri e is thought to be rich in the element carbon, which can exist in a variety of structural forms such as graphite (the material used as pencil lead), graphene, or diamond.
