Researchers have synthesized millimetre-scale hexagonal diamond, a crystal structure so elusive that many physicists doubted ...

Diamonds are famous for their strength, but scientists have long suspected that another form of diamond might be even harder.

A Chinese research team has produced bulk hexagonal diamond, a crystal structure long theorized to be harder than ...

Diamond is famously known as the hardest mineral on Earth. “There are hundreds of claims from people who believe they have seen it,” says Oliver Tschauner, a mineralogical crystallographer at the ...

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

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 ...

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

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 ...

Researchers have used a diamond sheet and salt film to make hexagonal salt crystals. Sodium chloride is massively common in our universe, but still full of surprises. The scientists used a ...
