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

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

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

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

Scientists created a pure hexagonal diamond in the lab, confirming a long-debated carbon structure slightly harder than natural diamonds.

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, ...

Atomic structure of the hexagonal diamond. Image from the study. Researchers named it lonsdaleite, after crystallographer ...

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 ...
