What’s harder than diamond?
wurtzite boron nitride(PhysOrg.com) — Currently, diamond is regarded to be the hardest known material in the world.
But by considering large compressive pressures under indenters, scientists have calculated that a material called wurtzite boron nitride (w-BN) has a greater indentation strength than diamond..
What is the strongest glass on earth?
Researchers have made a metallic glass that is the strongest and toughest material ever made. The Golden Gate bridge is made out of a relatively low strength steel, so it won’t break when an earthquake rattles the Bay Area.
What is the second hardest stone on earth?
MoissaniteMoissanite: The Second Hardest Mineral in Nature after Diamond | Blue moissanite, Minerals, Gemstones.

Is Obsidian stronger than diamond?
Surprisingly, the edge of a piece of obsidian is superior to that of a surgeon’s steel scalpel. 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. Obsidian is found all over the world.
What stone is as strong as a diamond?
moissaniteOn the Mohs scale, moissanite scores a 9.25, a very good score that makes it one of the hardest substances on earth, and very suitable for everyday wear as an engagement ring. Diamonds are the hardest known mineral and receive a 10 on the Mohs Scale of Hardness.
What is the weakest gem?
talcThe weakest MATERIAL is talc. This is drilled into every geology & geography student when learning Mohs Scale. A mineral has to be strong enough to be cut and polished to be a gemstone.
What is the toughest material on earth?
NacreNacre, the rainbow-sheened material that lines the insides of mussel and other mollusk shells, is known as the toughest material on Earth.
Is quartz harder than diamond?
Diamond is always at the top of the scale, being the hardest mineral. There are ten minerals in Mohs scale, talc, gypsum, calcite, fluorite, apatite, feldspar, quartz, topaz, corundum, and for last and hardest, diamond.
What is the hardest rock in the world?
Diamond is the hardest known mineral, Mohs’ 10.
What’s the strongest thing on earth?
Graphene, which was heretofore, the strongest material known to man, is made from an extremely thin sheet of carbon atoms arranged in two dimensions.
Which is the softest rock on Earth?
talcThe name for talc, a sheer white mineral, is derived from the Greek word talq, which means “pure.” It is the softest rock on earth.
Is Obsidian the strongest rock in the world?
Obsidian is a type of igneous rock that is formed from volcanic lava. It’s actually called ‘volcanic glass’ because of its shiny, glass-like appearance. Obsidian has a hardness rating of 5-6 on Moh’s Hardness Scale.
What gems are as hard as diamonds?
