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

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

After decades of debate, researchers say that they have found the clearest evidence yet for this rare form of carbon ...

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

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

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 ...

A team of researchers has reported the first laboratory synthesis and recovery of bulk hexagonal diamond, a crystal form long predicted to be harder than the conventional gems used in cutting tools ...

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 ...

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 ...
