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

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 ...

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

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 ...

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 ...

A team of physicists, materials scientists and engineers affiliated with several institutions in China, working with a colleague from Umeå University, in Sweden, has grown a diamond that is harder ...

In brief: Chinese researchers have developed a synthetic diamond that is significantly harder and more resilient than those that occur naturally here on Earth. If commercially viable, the new diamond ...
