could be used to fortify industrial tools like drill bits and saw blades - AND teach us about the evolution of earth.

Is there anything harder than a diamond?

It is well-known since the late 20th-century that there's a form of carbon that's even harder than diamonds: carbon nanotubes. By binding carbon together into a hexagonal shape, it can hold a rigid cylindrical-shaped structure more stably than any other structure known to humankind.

What is the hardest stone after diamond?

What is the hardest stone in the world?

Diamonds are the hardest stone, while talc (for example) is a very soft mineral. The scale by which the hardness of minerals is measured is the Mohs Hardness Scale, which compares the resistance of a mineral to being scratched by ten standard reference minerals that vary in hardness.

What are the top 5 hardest gemstones?

Diamond is graded the hardest (10), followed by ruby and sapphire (9), topaz, emerald and spinel (8), and garnet, tourmaline and quartz (7). The softest stones include talc (1), gypsum (2), calcite (3) and fluorite (4).

Is there a rock harder than diamond?

(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 most powerful gem?

DIAMOND. Properties: Relationships, love, and mental clarity. It's the strongest gemstone, so it's only fitting that diamonds are said to bond people together (and not just because they're so pretty).

What stone is as strong as a diamond?

Moissanite, a naturally occurring silicon-carbide, is almost as hard as diamond. It is a rare mineral, discovered by the French chemist Henri Moissan in 1893 while examining rock samples from a meteor crater located in Canyon Diablo, Arizona. Hexagonal boron-nitride is 18% harder than diamond.

What stone is worth more than a diamond?

Painite. The most valuable gem that is not a diamond is one that many have never heard of. Painite is an interesting brick-coloured gemstone. It is the most valuable non-diamond gem priced at £41,000-£49,000 ($50,000-$60,000 US) per carat.

What is the 2nd hardest material?

Boron nitride

c-BN is chemically and thermally stable, and is commonly used today as a superhard machine tool coating in the automotive and aerospace industries. But cubic boron nitride is still, at best, just the world's second hardest material with a Vickers hardness of around 50 GPa.

What rock is impossible to break?

Igneous rocks are formed from molten rock called magma. They are mostly crystalline (made up of interlocking crystals) and usually very hard to break.
