Laid out like an orchestra in a quiet gallery room, 40 colorful gems have one of the planet’s most distinguished conductors: a red diamond, 2.33 of the rarest carats in the world, shining like a ...

Thanks to the crystal structure of diamonds, with carbon atoms arranged into a lattice-like structure, diamond is top of the hardness scale, which is why it is used to cutting and drilling, as well as ...

gradually changing the molecular structure and transforming the carbon into pure diamond. To be clear, these diamonds aren’t just similar to a natural diamond; they are identical down to the ...

A big, beautiful diamond. Sure, it catches light like no other gem, and it's the hardest material on Earth, and it's worth an awful lot of money. But what is it really but a collection of ordinary ...

A new study indicates that Mercury's core-mantle boundary (CMB) may possess a diamond layer that extends up to 18 kilometers ...

Under the extreme heat and pressure, the carbon atoms in the material were forced together, forming tiny diamonds, or nano-diamonds. This doesn’t prove diamond rain is happening out there ...

Narrator: Believe it or not, this is a diamond ... Both is made of carbon. It's the same element, just the different atomic letter structure, makes them so extreme opposite in the phenomenology ...

Image caption, LEFT: The structure of diamond showing each carbon atom joined to four others. RIGHT: The structure of graphite with atoms of carbon arranged in layers. Carbon fibres are long ...
