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

Molten carbon can form into either diamond or graphite. A new study shows how graphite can sometimes form even under conditions that should lead to diamond. (Getty Images) The graphite found in your ...

Researchers have synthesized millimetre-scale hexagonal diamond, a crystal structure so elusive that many physicists doubted ...

Scientists created a pure hexagonal diamond in the lab, confirming a long-debated carbon structure slightly harder than ...

The diamond was around 0.04 inches in size and exhibited more sturdiness and resistance compared to typical cubic diamonds.

Chinese scientists have created an artificial “super diamond” much greater in hardness than real ones, an advance that could lead to breakthroughs across several key industries that rely on the ...

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

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 ...

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 ...
