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 ...

ANU Associate Professor Jodie Bradby said her team – including ANU PhD student Thomas Shiell and experts from RMIT, the University of Sydney and the United States – made nano-sized Lonsdaleite, which ...

(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 ...

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 ...

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 ...

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 ...

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 ...

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 ...
