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. Can osmium kill you? Unfortunately, Osmium forms a nasty compound, Osmium tetroxide, when exposed to air.

Osmium crystals, which, unlike diamonds, can form only in laboratory settings, have stronger abrasion resistance and purportedly refract light at greater distances than the traditional engagement ...

Is osmium harder than diamond? The stiffest materials also tend to be the hardest ones. Although osmium is hard for a metal, it’s far softer than diamond, so when an estimate of its bulk modulus turned out higher than diamond, no one took it very seriously, says Hyunchae Cynn of the Lawrence Livermore National Laboratory in California.

Osmium holds up better than any other known material when squeezed at extremely high pressures in a diamond anvil (above). Diamond is the hardest material, resisting scratches, dents, and chipping better than any other, so industrial strength machine tools often have diamond tips. But theoretically predicting new superhard materials is, well, hard.

Question: why is diamond so much harder than graphite?

Graphite and Diamond are different because they have different structures. However each carbon atom in Diamond has 4 covalent bonds with other Carbons, making it extremely strong and hard. On the other hand, each carbon in graphite is bonded to three carbons, and therefore graphite is formed in layers. Why is diamond so hard and strong?
