Researchers have produced nearly pure hexagonal diamond, a material long theorized to be harder than conventional diamond, by ...

“These findings resolve the long-standing controversy on the existence of hexagonal diamond,” researchers said.

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

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 ...

After decades of chasing after a rare hexagonal diamond, a Chinese team says their iteration of the elusive material is the ...

To misquote a famous song, "Diamonds are industry's best friend." Cubic diamond is the hardest mineral on Earth and is used in everything from precision cutting tools to high-performance ...

In brief: Chinese researchers have developed a synthetic diamond that is significantly harder and more resilient than those that occur naturally here on Earth. If commercially viable, the new diamond ...

In 1967, a hexagonal form of diamond, later named lonsdaleite, was identified for the first time inside fragments of the Canyon Diablo meteorite, the asteroid that created the Barringer Crater in ...

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 ...
