en.wikipedia.org/wiki/Superhard_material

A superhard material is a material with a hardness value exceeding 40 gigapascals when measured by the Vickers hardness test. They are highly incompressible solids with high electron density and high bond covalency.As a result of their unique properties, these materials are of great interest in many industrial areas including, but not limited to, abrasives, polishing and cutting tools and wear ...
