In theory, it appears that your statement is true.
According to Wikipedia:
"...The bulk modulus [resistance to uniform compression] of compressed [nanotubes] was 462.546 GPa [a measure of tensile strength], surpassing the value of 420 GPa for diamond." (Read more, below.)
In practice, however, since a carbon nanotube measures about 1/50,000th of the width of a human hair, any scratch accomplished on a diamond could likely escape any gemologist's inspection.

A diamond is an example of and element compound or mixture?
A perfect/pure diamond is made exclusively of carbon (the element). The specific conditions (temperature, pressure, time) that are required for diamonds to form and the fact that a carbon atom has four free electrons allow it to settle in the form of a crystal; that crystal is what we call the diamond. Given the strength of the links between the atoms; the diamond is the hardest natural solid on our planet. It's also important to note that graphite is also pure carbon but the way the carbon atoms are linked to each other (the number of electrons shared between each atom is two vs. one for the diamond) gives it completely different properties. The carbon atoms form layers and the graphite is soft and slippery; which makes it a nice dry lubricant that is sometimes used in lock cylinders. It's also opaque; unlike diamond. Diamond is an element, an allotrope of carbon.
What materials could you make a real diamond?
All diamonds, whether natural stones or man-made are always formed from carbon.
Are diamonds indistuctable?
By indestructible, you mean de-valued, then yes. One can scratch a diamond or chip it accidentally and it will be worth less. By indestructible, you mean obliterated, then probably not. Diamond has the highest melting point of any known mineral. Attempting to smash it would only produce diamond dust -- if indeed you could smash it, which is useful.
Does diamond have a melting point?
Yes, the highest melting point of any natural mineral, 3,550 C or 6,422 F.
Diamond and graphite are of carbon?
Diamond and graphite are both composed of carbon, but they are physically different from each other. Diamond is the hardest mineral known, is usually transparent and very abrasive. Graphite on the other hand, is soft, opaque and a very good lubricant.
Could diamond scratch another diamond?
Yes, in fact, it is the only way to scratch a diamond.
i was wondering if anyone could test what I beleive to be rough dimonds?
try to scratch tough glass with your rough diamond, if it makes good scratch then it can be a diamond
What are the three forms of pure carbon?
This isn't really a good question because there are more than three forms of carbon. Allotropes of carbon include: Amorphous Carbon Graphite Diamond Lonsdalite C60 (Buckminsterfullerene) C70 C540 Carbon Nanotubes Since it's pretty clear this is a homework question, I'm gonna suggest you answer with the first three forms. Your teacher might call amorphous carbon something else, so don't blame me if you get marked down. Of course you could always find the answer in your textbook (novel concept..)
What does this solid carbon become part of?
Solid carbon (C) may be diamond, graphite, coal, carbon black etc.
What are the pure forms of carbon?
Charcoal - a form of non-crystalline carbon Graphite - crystalline carbon - known as 'pencil llead' (although there is no lead in it!). In graphit, the atoms are joined together in flat sheets. Diamond - crystalline carbon with the carbon atoms arranged differently from graphite - in a huge 3d matrix. Buckminsterfullerene - a newly dicovered form of carbon where the atoms are joined together in hollow balls (called 'bucky-balls'). The investigation into this form of carbon in the future may lead to carbon 'nanotubes' - hollow tubes made out of elongated bucky-balls. These tubes, it is believed, will produce carbon that is immensely strong - like fibres as thin as your hair that could support the weight of a bus.
What is the cost of carbon in diamond form?
Its tricky, carbon in Diamond form means "Diamond",it could cost from a couple of Dollars a carat (Industrial) to say 2000 Dollars a carat(Gem quality) or more.........
What minerals can scratch glass?
Any mineral with roughly a hardness of 6 or more on the Mohs scale of mineral hardness could scratch glass, which is roughly 5.5 on the Mohs scale. Some minerals that could scratch glass would be quartz, topaz, corundum, and diamond.
Mineral X is scratched by a diamond. Mineral X .?
Mineral X could be anything. Diamond is the hardest mineral (10 on Mohs' scale) and can scratch all other minerals including another diamond.
What is the hardest substane in the world?
Diamond (Crystalline Carbon) or Possibly a Known as 'Carbon whiskers' or 'Carbon Nano-rods' But that could have limited use's because of possible biological hazards.
What are the Uses of diamond due to its properties?
a diamond has no special properties Your sort of right but a diamond is the allotrope carbon of where the carbon atoms are arranged in the specific type of cubic lattice called diamond cubic. Diamond is an optically isotropic crystal that is transparent to opaque. I might be wrong though!
Can any chemical melt diamond?
Diamonds are the hardest known natural material (from Carbon) and with a melting point of over 3500`c it would be pretty much impossible to melt one down. Only another diamond can scratch a diamond but it wont melt it.
Can diamond scratch other rocks?
Yes, diamond is the hardest mineral.A field test for diamond is extreme hardness, which you could verify by scratching a rock with your unknown sample. If the rock is scratched, you could bag the sample and ask for further tests to determine the composition of the sample.(If, however, what you're questioning is a gem stone, scratching rocks with it could be an expensive test.)
