What’s harder than a diamond?
wurtzite boron nitrideSource: English Wikipedia. (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.
Will sandpaper scratch a diamond?
Diamonds are among the world’s hardest stones. Consequently, it wouldn’t be scratched by the rough surface of the sandpaper. … If you scratched it with a sandpaper it would scratch up just like any other material that is not a diamond.

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. Steel, on the other hand, has an ionic structure.
Are Diamonds bulletproof?
Diamond Armor is certified bulletproof by NATO standards, waterproof thanks to nano-technology sealing and has an EMPA air conditioning system in-built to keep the wearer cool.
Can a bullet break a diamond?
Yes, but only in unusual circumstances. The other answers have hopefully driven home the difference between hardness and toughness. A bag of diamonds a few inches thick would stop a bullet because shattering the diamonds would use up the bullet’s kinetic energy.
Do diamonds need to breathe?
Hi Donna, When a jeweler talks about a diamond needing to breathe, he is referring to the light needed to sparkle. If the diamond is too covered up, it has no air and will not sparkle. Diamonds don’t always have holes and cz’s are not always covered up.
