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.

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 ...

Diamond is famously known as the hardest mineral on Earth. “There are hundreds of claims from people who believe they have ...
