The reason diamond is so hard has to do with the arrangements of carbon atoms in its crystalline form, which has a very high packing factor. So even the hardest bedrock is still not as hard as diamond. Below are the 10 strongest materials known to man:. One-atom-thick sheets of carbon are times stronger than steel.
Here, the list of 10 strongest animals in the world based on strength to weight ratios. The half inch long dung beetles are the strongest living creatures on Earth. In a study set to come out this month in the Journal of the Royal Society Interface, British researchers announced that the teeth of shelled, aquatic creatures called limpets are the strongest biological material on Earth, overtaking the previous record-holder, spider silk.
But in most probably , it lost it's title to wurtzite boron nitride and mineral lonsdaleite. The first, wurtzite boron nitride has a similar structure to diamond, but is made up of different atoms.
The second, the mineral lonsdaleite , or hexagonal diamond is made from carbon atoms just like diamond, but they are arranged in a different shape. Diamond was once thought to be the hardest and the most incompressible material on earth, either natural or man-made. Although diamond is still considered the hardest, the bulk modulus of the metal osmium has recently been found to be GPa. Tungsten has the highest tensile strength of any natural metal, but it's brittle and tends to shatter on impact.
Titanium has a tensile strength of 63, psi. Chromium, on the Mohs scale for hardness, is the hardest metal around. Well-crafted obsidian blades, as with any glass knife, can have a cutting edge many times sharper than high-quality steel surgical scalpels, the cutting edge of the blade being only about 3 nanometers thick.
Don Crabtree produced obsidian blades for surgery and other purposes, and has written articles on the subject. Diamond is currently thought to be the hardest natural material on Earth, having a hardness of ten out of ten on the Mohs scale of mineral hardness.
Diamond is made up of carbon atoms which share strong covalent bonds where electrons are shared between atoms and are equally spaced in a lattice arrangement.

Judging from the weathered look of this Diamonds however are also brittle.
Obsidian has a hardness of 5 to 5. Scientists have calculated that wurtzite boron nitride and lonsdaleite hexagonal diamond both have greater indentation strengths than diamond. Source: English Wikipedia. Obsidian is a type of igneous rock that is formed from volcanic lava. Diamonds are not particularly rare. Summary: A team of scientists has calculated the strength of the material deep inside the crust of neutron stars and found it to be the strongest known material in the universe.
Topping the list, graphene is the strongest materials known to humans. The diamond mining industry is destroying our environment. A lot of diamond mining is unregulated and therefore there is no control over its impact on the environment. Is Obsidian sharper than diamond? Diamonds are not however bulletproof in general, as while they are hard, they are not particularly tough and their brittleness will cause them to shatter when struck by a bullet.
Bulletproof glass is made from layered smooth flawless glass with a very specific chemistry and plastics to stop a bullet. Obsidian is full of impurities and other flaws that would make this process impossible.
