No, the hardest material known is diamond.
Edit: Actually, diamond is only the hardest material which occurs naturally in macroscopic crystalline form. While the lonsdaleite found in meteorite craters has a Mohs hardness of about 7-8 (as opposed to diamond's 10), this is due to impurities and imperfections. It has been calculated that a pure lonsdaleite crystal would be 58% harder than diamond. Similarly, a crystal of wurtzite boron nitride would also be harder than diamond, although a method of producing such crystals is still to be found.
ADNR's are a special manmade form of pure carbon that are harder (and denser) than natural diamonds and manmade ultrahard fullerine. I believe the answer is lonsdaleite. It is naturally made and is 58% harder than diamonds.
Diamond has always been considered the hardest natural substance in the world. However, wurtzite boron nitride and mineral lonsdaleite have recently been discoverd and are much harder than diamond.
Diamond is the second hardest material found in nature. It was always thought to be the hardest, but scientists have recently discovered a material called Ionsdaleite which is 58% harder than Diamond.
steel boron carbide is stronger than steel I do believe To date, probably carbon nanorods. Carbon is strongest, but in might be nanorods, nanotubes, or fiber. I'm not sure. A particular arrangement of carbon called Lonsdaleite (both naturally occurring in trace amounts and manufactured) is the hardest known material to date. pure samples have been recorded to be 58% harder than diamond, however when found naturally, impurities cause the Mohs Hardness to be only 7-8 (diamond is 10 on this scale).
Diamond :)
The second hardest substance in the world is mineral lonsdaleite, or hexagonal diamond. It's made up from the same materials as diamonds, but it has a slightly different structor. Mineral lonsdaleite is extremely rare in nature.
The hardest material known to man is currently called lonsdaleite (a carbon form), which is approx. 58 % harder than a diamond and then there is wurtzite boron nitride which is about 18% harder than diamond. Both occur in nature just like diamonds.
For many years, scientists identified diamond as the hardest substance on earth. However, the girl's best friend has been surpassed by Wurtzite Boron Nitride (#1) and Lonsdaleite (#2). Lonsdaleite is not a natural earth substance, since it is composed of what is left after meteoroids strike earth. Wurtzite Boron Nitride has a chemical structure similar to diamond, but is strengthened by some additional chemical bonds forged within volcanos.

Nowhere, I also searched the whole internet (3 google pages) but I didnt find it. However, I own a possible chunk of the material (113 grams). I searched for all of the features lonsdaleite contains and it seems that it all matches. bye
Yes, they are but the hardest material in the world known to mankind is DIAMOND.
Diamond has an extremely strong covalent bonding between carbon atoms; today diamond is not considered the hardest material, Today the hardest material is Aggregated diamond nanorods.
diamond is the hardest material and if it is sharpened , then it is the sharpest material

Diamond ( an allotrope of carbon) is the hardest material known.
