Diamonds are famous for their strength, but scientists have long suspected that another form of diamond might be even harder.

Researchers made small, pure samples of the elusive mineral lonsdaleite – also known as hexagonal diamond — and tested its ...

Chinese scientists claim to have created the long theorized hexagonal diamond, stronger than the real thing, and only found until now at sites of meteorite impacts. The commonly found cubic diamond is ...

Researchers have synthesized millimetre-scale hexagonal diamond, a crystal structure so elusive that many physicists doubted ...

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

A Chinese research team has produced bulk hexagonal diamond, a crystal structure long theorized to be harder than ...

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

Scientists created a pure hexagonal diamond in the lab, confirming a long-debated carbon structure slightly harder than natural diamonds.

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

Researchers in China have made what they claim to be the first samples of pure hexagonal diamond, a theorised rare variant of superstrong diamond found in meteorites from shattered dwarf planets, ...
