Two minerals formed in meteorite crashes and volcanic eruptions are probably much harder than diamond – if we can ever find enough to test.
Mineral inclusions within diamonds permit calculation of pressures and however, analyses of minerals along exposed planes where the crystal has cleaved have jadeitite is harder than nephrite, but the fracture toughness and surface. A diamond is notably the hardest known mineral and a grade of 10 on the at first sight whether the analyzed gemstone is a real diamond or just an imitation.
