Diamond is famously known as the hardest mineral on Earth. “There are hundreds of claims from people who believe they have seen it,” says Oliver Tschauner, a mineralogical crystallographer at the ...

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.

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 ...

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 ...

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 ...

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 ...

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 ...
