Diamonds are famous for their strength, but scientists have long suspected that another form of diamond might be even harder. Evidence of this was gathered over the past sixty years in meteorite ...

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 ...

Research teams from Wuhan University and the China University of Geosciences (Wuhan) have revealed new insights into the formation mechanism of nitrogen-vacancies (NV) centers in type-Ib diamonds, a ...

Paving the way to a dry process with less environmental impact Tools coated with diamond film (diamond-coated tools) are used for difficult-to-machine materials such as CFRP. In the manufacture of ...

Researchers have succeeded in creating a rare type of diamond, known as lonsdaleite or hexagonal diamond. This material, whose hardness could surpass that of conventional diamonds, opens new ...

Diamond, with its tough-to-break carbon lattice of interlocking cubes, is traditionally considered the hardest material on Earth. Yet a rare form of diamond known as lonsdaleite—a crystal with carbon ...

New research indicates that a rare form of diamond may originate in the burbling cores of distant worlds, arriving on Earth thanks to violent cosmic collisions. According to a team of scientists 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 ...
