A team of researchers has reported the first laboratory synthesis and recovery of bulk hexagonal diamond, a crystal form long predicted to be harder than the conventional gems used in cutting tools ...

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

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 ...

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

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

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

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 ...

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 ...
