Which is the hardest element in the Earth?

The hardest element is Titanium. Diamond is the hardest & purest but it is not found as in abundance as Titanium.

Diamond is the purest form of carbon with no impurities but they are rare compared to other carbon forms in the mines including peat, anthracite etc. Pure titanium is found in abundance. So according to hardness it's Diamond but it's considered Titanium because it's in larger quantity.

Diamonds are the hardest materials which are used to cut glass and steel.They are made of carbon.
In 1822, a German mineralogist , Friedrich Moh came up with a way to classify a mineral by how hard it is. Moh's scale of hardness takes 10 most common minerals on earth and ranks them by their hardness.
1. Talc- softest
2.Gypsum
3. Calcite
4. Fluorite
5. Apatite
6. Feldspar
7. Quartz
8. Topaz
9. Corundum
10. Diamond- hardest

Carbon in the allotropic form Diamond is hardest element.
Carborundum is next but its a compound of silicon and Carbon ( SiC).
Aluminium Oxide, Al2O3, and other carbides and nitrides of various elements ( Vanadium, Boron Steel) are also known hardest material.

First off, diamaonds aren't elements. Diamond is made of carbon, just like the 'lead' in your pencil. Second, diamond is not the hardest substance on earth, it's just one of the harder natural materials on earth. Third, lots of things can scratch diamonds, sand, dirt, dust, even water can scratch diamonds. One easy way to shape diamonds very precicely is by ablating (sanding) the diamond's surface with a laser beam. I hope this clears up some confusion. Cheers.

Lutetium is the hardest of the 'rare earth elements'...

or

if you are considering allotropes or minerals it has to be carbon in the form of diamond...that's for sure!

Carbon!!
Diamond is the hardest substance found in Earth ad it is an allotrope of carbon.
