What is the strongest mineral in the world?

1. Diamond. Diamond is the hardest known natural mineral according to the Mohs scale. Its hardness depends on its purity, and the hardest diamond can only be scratched by other diamonds.

What can scratch a diamond?

Yes, it’s true, diamonds are the hardest substance on earth, and can only be scratched by other diamonds. But if you’re doing the scratch test where you rub it against another stone or with sandpaper and it’s not a diamond, you’re only going to ruin the stone you’re scratching!

Which is the softest mineral found inside the Earth?

TalcTalc 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.
