Graphene is formed by peeling extremely thin layers of graphite off of a larger piece, in the original paper published on graphene it was done using tape.
The molecular structure of graphene differ from the other allotropes of carbon diamond and graphite in that graphene consist of a single layer of atoms.
It would take an elephant, balanced on a pencil, to break through a sheet of graphene the thickness of Saran Wrap."

It's not both graphite graphene and dimond are pure forms of carbon. Dimond is just has a different arrangement of atoms that make is very hard and transparent.
When carbon forms sheets when it bonds to three other carbon atoms they are called graphene. Nanotechnology researchers have designed graphene sheets only as thick as a carbon atom.
Graphene is a sheet of Carbon atoms, or one layer of Graphite ("lead" in a pencil). A graphene filter is a filter made of graphene.
Graphene is pretty amazing. An adequate description of the properties is rather long. There is a link below to the properties section of an article on graphene.
Graphene, graphite, and some carbon nanotubes can all conduct electricity.
Graphene is a very thin layer of graphite. It is so thin, it is so close to being invisible!
The molecular structure of graphene differ from the other allotropes of carbon diamond and graphite in that graphene consist of a single layer of atoms.
In for form of graphite it can be broken into graphene sheets. In other forms carbon does not break into sheets.
graphene according to how much it can hold (calculator) and how dense it is.
