Is buckminsterfullerene harder than diamond?
The fullerene molecule has excellent mechanical rigidity.
At the same time, the fullerite crystal is a soft material under normal conditions, but becomes harder than diamond under pressure (due to the 3-D polymerization)..
What can damage a diamond?
Sudden extreme temperature changes can cause damage, however. Diamonds can chip or fracture from hard impact, especially in areas where the carbon atoms are not tightly bonded. These areas, called cleavage planes, are the major source of damage to diamonds (figure 2).
What is the hardest material in the world?
(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.
What is the softest mineral on Earth?
TalcTalc is the softest and diamond is the hardest. Each mineral can scratch only those below it on the scale.

Is Bedrock harder than diamond?
It is impervious to anything else in that universe. 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.
Is Obsidian stronger than diamond?
Diamond is harder than obsidian, as obsidian is a form of volcanic glass. … Obsidian has a hardness of 5 to 5.5 on the mineral hardness scale, whereas diamonds have a hardness of 10.
Can I 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.
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 rock in the world?
The strongest rock in the world is diabase, followed closely by other fine-grained igneous rocks and quartzite. Diabase is strongest in compression, tension, and shear stress. If mineral hardness is the determining factor of strength then diamond is technically the strongest rock in the world.

Is anything stronger than diamond?
Each carbon atom forms four bonds with its neighbors, explaining the overall stability and hardness of the crystal structure. Although diamond is commonly mentioned as the hardest mineral, there are minerals that are harder. Moissanite, a naturally occurring silicon-carbide, is almost as hard as diamond.
