To synthesize the crystals, the team compressed highly ordered pyrolytic graphite to pressures as high as 20 gigapascals, ...

A Chinese research team has produced bulk hexagonal diamond, a crystal structure long theorized to be harder than ...

Diamonds are famous for their strength, but scientists have long suspected that another form of diamond might be even harder.

Atomic structure of the hexagonal diamond. Image from the study. Researchers named it lonsdaleite, after crystallographer ...

The graphite found in your favorite pencil could have instead been the diamond your mother always wears. What made the difference? Researchers are finding out. How molten carbon crystallizes into ...

Researchers made small, pure samples of the elusive mineral lonsdaleite – also known as hexagonal diamond — and tested its ...

Australian scientists have discovered strangely folded diamonds in rare meteorite samples. In investigating how they came to form, the team found evidence that they were forged in a cataclysm on an ...

Diamonds are famous for their strength, but scientists have long suspected that another form of diamond might be even harder.

Molten carbon can crystallize into diamond or graphite, but it has been difficult to study this process. New simulations show that graphite can sometimes "hijack" the pathway that would lead to ...
