Diamond is well-known for being the hardest natural material on Earth, though synthetic forms have been developed that are even tougher – a feat that researchers have managed again, through a new ...

A mystery that puzzled scientists for more than half a century may finally have an answer. The strange crystals hidden in a famous Arizona meteorite have now been recreated in a lab, and they could ...

(Nanowerk News) A new study by Washington State University researchers answers longstanding questions about the formation of a rare type of diamond during major meteorite strikes. Hexagonal diamond or ...

Scientists have created the first sizable meteorite diamond — also known as lonsdaleite or hexagonal diamond — a material predicted to be even harder than the diamonds normally found on Earth. The ...

In a major scientific milestone, Chinese researchers have successfully synthesised a rare form of diamond found naturally only in meteorites, the hexagonal diamond, marking a leap forward in the quest ...

Hexagonal diamonds are formed when graphite is subjected to strong impact and heat, such as due to a meteorite impact. While ordinary diamond has a structure called cubic, hexagonal diamond is ...

A team of researchers has for the first time observed and recorded the creation of hexagonal diamond under shock compression, revealing crucial details about how it is formed. The discovery could help ...

Scientists have detected the presence of a rare "folded diamond" that arrived on Earth from outer space via an asteroid. The material found is known as lonsdaleite, and like a diamond, it's made out ...

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 ...

Currently, diamond is regarded to be one of the hardest and most scratch-resistant natural materials in the world. Most diamonds found in nature and often used in jewelry display a cubic crystal ...
