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

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 ...

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

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 ...

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

A team of Chinese scientists may have cracked the secret behind the strange Canyon Diablo diamonds. Hexagonal in form rather than cubic, the process behind how these diamonds formed has, until now, ...

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

After decades of debates over the existence and properties of one of the world’s ...

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 ...

Researchers from Pohang University of Science and Technology (POSTECH) and the University of Montpellier have successfully synthesized wafer-scale hexagonal boron nitride (hBN) exhibiting an ...

A water droplet freezes around a dust particle in the air, creating an ice crystal. More water molecules land on the crystal and create the hexagonal shape as they extend six ways to form arms. The ...
