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 ...

“These findings resolve the long-standing controversy on the existence of hexagonal diamond,” researchers said.

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

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 ...

An international research team has produced a bulk, millimeter-scale hexagonal diamond in the laboratory, a crystal variant long theorized to rival or exceed the hardness of the cubic diamonds found ...

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 ...

For the first time, researchers have hard evidence that human-made hexagonal diamonds are stiffer than cubic diamonds found in nature and often used in jewelry. Hexagonal diamonds have been found at ...

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 ...

Scientists from China have claimed they might have found a mineral that is harder than the cubic diamond, which is known to the world as the hardest existing mineral. The hexagonal diamond (HD) is ...
