What’s harder than diamond?

wurtzite boron nitride(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 Obsidian stronger than diamond?

Surprisingly, the edge of a piece of obsidian is superior to that of a surgeon’s steel scalpel. It is 3 times sharper than diamond and between 500-1000 times sharper than a razor or a surgeon’s steel blade resulting in easier incisions and fewer microscopic ragged tissue cuts. Obsidian is found all over the world.
