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 mineral is stronger 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.
What is the weakest mineral in the world?
Talc is the softest mineral on Earth. The Mohs scale of hardness uses talc as its starting-point, with a value of 1. Talc is a silicate (like many of the Earth’s most common minerals), and in addition to silicon and oxygen, contains magnesium and water arranged into sheets in its crystal structure.
What if I hit 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 steel incredibly strong and infinitely workable. Diamonds, because of their lack of flexibility in the structure, are not actually very strong at all.
