Can minerals scratch themselves?

A minerals rating on the hardness scale is determined by a scratch test. For example the diamond is the hardest mineral because no other mineral on the scale is able to scratch it. Since Fluorite is a 4 on the scale it means that fluorite can scratch all the minerals below it but not be scratched by them.

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.

What’s harder than diamond?

Moissanite, a naturally occurring silicon-carbide, is almost as hard as diamond. It is a rare mineral, discovered by the French chemist Henri Moissan in 1893 while examining rock samples from a meteor crater located in Canyon Diablo, Arizona. Hexagonal boron-nitride is 18% harder than diamond.

Are Diamonds bulletproof?
