(PhysOrg.com) — Currently, diamond is regarded to be the hardest known material in the world. But by considering large compressive pressures under indenters, scientists have calculated that a material called wurtzite boron nitride (w-BN) has a greater indentation strength than diamond.
Is anything harder than diamond?
Diamonds remain the most scratch-resistant material known to humanity. … 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.
Which is harder diamond or iron?
Typical values of tensile strength of iron/steel varies from 100 to 11000 MPa. Therefore diamond can withstand more than iron/steel. The data you quote shows that diamond is stronger than steel, but strength isn’t the same as brittleness (or, indeed, stiffness).
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.
What is the only thing that can cut a diamond?
Diamond manufacturers cut a groove in the diamond with a laser or saw, and then split the diamond with a steel blade. Sawing is the use of a diamond saw or laser to cut the diamond rough into separate pieces.
Are Diamonds bulletproof?
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 is the strongest metal in the world?
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.
What is the strongest thing on earth?

Can you 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).
Can you sell a diamond you found?
The diamond ring that you found on the ground is not yours. If you wish to sell it to get the most value, it is advisible to go to a reputed certified dealer who in most probability will ask for the original purchase invoice and certificate.
Can you crush a diamond?
And yes, diamonds are extremely hard. However, that just means that they’re difficult (but possible) to scratch and chip on the surface. … However, if you took a hammer and hit a diamond at the right angle, it would easily shatter.
How diamonds look when they are found?
Looking at the crystal form is a quick way of differentiating diamond from most of the other minerals that look like diamond. Diamonds are cubic (isometric) form. The most common mineral that looks like a diamond is quartz and it is hexagonal form. … If you see six sides than you probably found quartz.
Can a waterjet cut a diamond?
Since diamond is the hardest material in the world, only the waterjet machine can cut it.”
What is diamond cut gold?
Diamond cuts are nothing more than notches or grooves cut into the metal (Usually made by a jeweler’s chisel). That’s it! A type of finish on the metal, just like satin finish, matte finish or sandblasting. Diamond cuts are just a simple jeweler’s trick to make the outer metal surface glisten.
