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

An international research team has produced a bulk, millimeter-scale hexagonal diamond in the laboratory, a crystal variant long theorized to rival or exceed the hardness of the cubic diamonds found ...

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 ...

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 ...

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 ...
