ADNR's are a special manmade form of pure carbon that are harder (and denser) than natural diamonds and manmade ultrahard fullerine. I believe the answer is lonsdaleite. It is naturally made and is 58% harder than diamonds.
The hardest element is chromium, which is in group 6.

One of the hardest stones known to man that the Olmec carved masks from is jadeite. This highly durable and lustrous material was prized for its beauty and significance, often associated with status and power in Olmec culture. The Olmec's ability to carve intricate designs from jadeite demonstrates their advanced craftsmanship and symbolic artistry.
Diamond is still the hardest substance known to man. Various carbides such as tungsten carbide, boron carbide, and silicon carbide are also extremely hard, but you will notice that they all contain carbon (diamond is pure carbon - the rest are carbon compounds.)

Diamond is the hardest known natural material on Earth, scoring a 10 out of 10 on the Mohs scale of mineral hardness.
Diamonds are the HARDEST natural material. Mankind has created harder artificial materials.
Diamond is the hardest mineral mined in the north of Western Australia. It has a hardness of 10 on the Mohs scale, making it the hardest natural material known to man.

I am the hardest riddle alive! wich comes first the Lego or my ego?
The hardest surface on Earth is diamond. It is considered the hardest because of its strong molecular structure, which consists of carbon atoms arranged in a tightly bonded crystal lattice. This structure makes diamond extremely resistant to scratching and abrasion, making it the hardest naturally occurring material known to man.
