Natural diamond, seen here, has a cubic packing structure. But a much rarer form of diamond has hexagonal packing and has now ...

The brilliantly shiny diamond is more than just pretty; it's one of the hardest minerals on Earth, with a name derived from ...

Ordinary diamonds have a cubic lattice, but hexagonal diamonds have carbon atoms bonded in a hexagonally symmetric ...

Hexagonal diamond up to 60 per cent stronger than normal diamonds could be used to create super-tough drilling and cutting ...

Diamonds are precious. They’re valued for their beauty but they also have some incredible real-world applications. Thanks to its incredible hardness, diamond is often used … ...

Scientists have discovered how a rare form of diamond is created in space. Found in four meteorites in north-west Africa, the strange hexagonal diamonds do not naturally occur on Earth. Now, we ...

The material found is known as lonsdaleite, and like a diamond, it's made out of carbon. The difference is that its crystal structure is arranged in a hexagonal pattern, so lonsdaleite is ...

Chinese scientists have created an artificial “super diamond” much greater in hardness than real ones, an advance that could lead to breakthroughs across several key industries that rely on the ...

The ‘super diamond’ structure exhibits high thermal stability ‘up to 1,100°C and a very high hardness of 155 Giga Pascals (GPa)’, according to the research, published in the Nature ...
