boron nitrideThe 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.

Are teeth harder than rocks?

How would you know if a diamond is real?

To tell if your diamond is real, place the stone in front of your mouth and, like a mirror, fog it up with your breath. If the stone stays fogged for a few seconds, then it’s probably a fake. A real diamond won’t fog up easily since the condensation doesn’t stick to the surface.
