Actually...
When talking about Naturally occurring substances, then your answer is Diamond. It is an allotrope of the element Carbon (another allotrope of carbon is the pitch of your pencil !!!:-)).
When talking about all the substances, the flag goes to a certain Boron Nitride, chemical formula BN, which is momentarily harder than diamond.
