Researchers have succeeded in creating a rare type of diamond, known as lonsdaleite or hexagonal diamond. This material, ...

At high temperatures and pressures, molten carbon has two options. It can crystallize into diamond and become one of the ...

Researchers Developed a New Kind of Diamond From a Meteorite — And It's 58% Harder Than a Normal Diamond A new kind of ...

Through the simulations, the team also revealed the molecular structures of liquid carbon as it crystallized into graphite and then, separately, as liquid carbon crystallized into diamond.

Rare diamonds found in meteorites called ureilites have a folded hexagonal structure. Learning the process of how they were formed could inspire better lab-grown diamonds.

The structure, an interlocking form of graphite and diamond, has unique properties that could one day be used to develop superfast charging or new types of electronics, researchers say.

Mercury could have a thick underground layer of diamonds, scientists say. Some of the stones may have found their way to the surface, according to a recent study.

Despite—or rather, because of—Mercury’s tumultuous early years, it could now be a diamond-encrusted world. Space rocks that smashed into the graphite that blankets much of the planet could ...
