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

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 ...

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

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 ...

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 ...

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 ...

A recent article in Scientific Reports detailed the characterization of disordered structures in graphene and monolayer hexagonal boron nitride (hBN) induced by low-energy argon ion irradiation. The ...
