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 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 ...

The diamond was around 0.04 inches in size and exhibited more sturdiness and resistance compared to typical cubic diamonds.

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

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

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, ...

To misquote a famous song, "Diamonds are industry's best friend." Cubic diamond is the hardest mineral on Earth and is used in everything from precision cutting tools to high-performance ...

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 ...

Scientists have created hexagonal diamonds that are stronger than their naturally occurring counterparts, Washington State University has announced. Though hexagonal diamonds aren't a new thing, past ...
