Diamond is the hardest naturally occurring substance found on Earth. But it is not the hardest substance. Wurtzite boron nitride (synthetic) and lonsdaleite (which comes from meteorites) are both harder.

Is ice harder than diamond?
The hardness of minerals ranges from 1 (for talc, to 10 for diamond”. Practically all minerals are technically harder than ice. … The hardness of minerals ranges from 1 (for talc, to 10 for diamond”.
Is Obsidian stronger than diamond?
Surprising Things about Obsidian
Surprisingly, the edge of a piece of obsidian is superior to that of a surgeon’s steel scalpel. It is 3 times sharper than diamond and between 500-1000 times sharper than a razor or a surgeon’s steel blade resulting in easier incisions and fewer microscopic ragged tissue cuts.
What’s harder than diamond?
The structure of boron nitride in its wurtzite configuration is stronger than diamonds. Boron nitride can also be used to construct nanotubes, aerogels, and a wide variety of other fascinating applications.
Is Bedrock harder than diamond?
In our universe, diamond has a hardness of 10 on the Mohs scale. … Bedrock can be made from many different substances, with a hardness anywhere from 1 to 9. So even the hardest bedrock is still not as hard as diamond.
What happens if you melt a diamond?
At ~700 degrees Fahrenheit the diamond will start burning. This will produce Carbon Dioxide and change the structure so that it is no longer a diamond. As diamond is made of Carbon, it would revert back to that form while losing its mass to the production of CO2. This is due to the presence of Oxygen.
Can We Make Diamond at home?
Synthetic diamonds are made at about 300deg C, but usually in a pressure vessel using microwave radiation and a “seeding” crystal. You can make diamond as big or small as you want by growing them in a chemically neutral environment (nobel gas/ nitrogen) using CO2. Check out wikipedia, has an article about them.
What is the strongest metal on earth?
In terms of tensile strength, tungsten is the strongest out of any natural metal (142,000 psi). But in terms of impact strength, tungsten is weak — it’s a brittle metal that’s known to shatter on impact.
Can you break a diamond with a hammer?
As an example, you can scratch steel with a diamond, but you can easily shatter a diamond with a hammer. The diamond is hard, the hammer is strong. … This makes the diamond incredibly hard and is why it is able to scratch any other material.
Can Obsidian cut through diamond?
Cutting edge
Obsidian – a type of volcanic glass – can produce cutting edges many times finer than even the best steel scalpels. At 30 angstroms – a unit of measurement equal to one hundred millionth of a centimeter – an obsidian scalpel can rival diamond in the fineness of its edge.
Can anything melt a diamond?
In the absence of oxygen, diamonds can be heated to much higher temperatures. Above the temperatures listed below, diamond crystals transform into graphite. The ultimate melting point of diamond is about 4,027° Celsius (7,280° Fahrenheit).
Are Diamonds bullet proof?
It doesn’t seem unreasonable to wonder whether diamonds are bulletproof, since diamond is the world’s hardest natural material. 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.
What can cut diamond?
Diamonds are cut with specialized tools that make use of diamond tipped phosphor bronze or diamond dusted steel blades. Such tools are used to exploit the structural weakness of the diamond by grooving and striking along specific tetrahedral planes.
What is the strongest thing in the universe?
The strongest material in the universe may be the whimsically named “nuclear pasta.” You can find this substance in the crust of neutron stars. This amazing material is super-dense, and is 10 billion times harder to break than steel.
