Diamond is the hardest known material to date, with a Vickers hardness in the range of 70–150 GPa. Diamond demonstrates both high thermal conductivity and electrically insulating properties, and much attention has been put into finding practical applications of this material.
Diamond was the hardest known naturally occurring mineral when the scale was designed, and defines the top of the scale, arbitrarily set at 10. The hardness of a material is measured against the scale by finding the hardest material that the given material can scratch, or the softest material that can scratch the given material.
A silvery substance, one of the hardest in the Pokémon world, and which only occurs on Silver Rock Isle. The locals sell wing-shaped pin talismans fashioned from silver rock stone. Silverstone Elemental Assassin: Magic metal that can absorb and negate elemental magic, at the cost of generating heat (melting the metal if it absorbs too much).
If it exists, nuclear pasta would be the strongest material in the universe. [1] Between the surface of a neutron star and the quark–gluon plasma at the core, at matter densities of 10 14 g/cm 3 , nuclear attraction and Coulomb repulsion forces are of comparable magnitude.

The precise tensile strength of bulk diamond is little known; however, compressive strength up to 60 GPa has been observed, and it could be as high as 90–100 GPa in the form of micro/nanometer-sized wires or needles (~ 100–300 nm in diameter, micrometers long), with a corresponding maximum tensile elastic strain in excess of 9%.
It is one of the hardest known materials, along with various forms of diamond and other kinds of boron nitride. Borazon is a crystal created by heating equal quantities of boron and nitrogen at temperatures greater than 1800 °C (3300 °F) at 7 GPa (1 million lbf/in 2 ).
The lower oxidation states are stabilized by the larger halogens, so that the trichloride, tribromide, triiodide, and even diiodide are known. The oxidation state +1 is known only for osmium monoiodide (OsI), whereas several carbonyl complexes of osmium, such as triosmium dodecacarbonyl (Os 3 (CO) 12), represent oxidation state 0.
