Diamond is the hardest naturally occurring substance on Earth.
Aggregated Diamond Nanorod are the hardest overall and un-naturally occuring substance on Earth. They are actually a group of tiny diamonds which are virtually un-compressable.
Hope this helped!

There is nothing harder than Diamond. In answering this question, 'on earth' must be assumed, since there is no reference to 'naturally occurring in the universe' implied or contained within the question.
One of the hardest substances on earth, only a diamond is hard enough to cut other diamonds. It is possible only because the hardness of diamond varies widely according to the direction in which one is trying to cut or grind. Therefore a harder diamond is used to cut one that is slightly softer (due to impurities).
a naturally occurring substance is one that can be randomized in between matter of existence for example: it is a substance you can create without knowing what it does so it occurs naturally. the synthetic substance is one of which a robot could relate to as it is a type of substance used within robotics and metallics of vehicles and other electrical equipment (synthetic meaning robotic) Firstly synthetic does not mean robotic. Look it up. Secondly I'm not convinced that the answer above would be right even if it was coherent. Naturally occurring denotes a substance that occurs in nature, in the right circumstances this can cover a wide variety of things. Synthetic substances are artificial or man made, generally for a specific purpose. Even some elements can be synthesized though these are incredibly unstable and thus not naturally occurring.

Diamond use to be the hardest known natural substance now it is the mineral lonsdaleite at 58% stronger then diamond is the first the second hardest is wurtzite boron nitride at 18% stronger then diamonds they are both extreamly rare natural minerals sources http://www.newscientist.com/article/dn16610-diamond-no-longer-natures-hardest-material.html

A diamond
Diamonds is not a stone it's crystal actually. But the hardest stone is granite stone.
Diamonds are the hardest known naturally occurring substance. Most diamonds are electrical insulators.
The hardest substance that is naturally occurring is a diamond. However, there are harder substances that have been made by scientists in labs.
Diamond is the hardest material on the list. It ranks as a 10 on the Mohs scale of mineral hardness, making it the hardest naturally occurring substance known.
Naturally occurring means that the substance is natural and is not in any way made by mankind.
