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

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

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

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 research team led by Sun Jian at Nanjing University has produced recoverable, millimeter-sized crystals of hexagonal diamond, a rare carbon polymorph that prior theoretical work has suggested could ...
