Scientists have discovered that an ancient "catastrophic collision" between a dwarf planet and an asteroid is responsible for the creation of a rare and mysterious cosmic gem. The findings, published ...

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 ...

Researchers have succeeded in creating a rare type of diamond, known as lonsdaleite or hexagonal diamond. This material, whose hardness could surpass that of conventional diamonds, opens new ...

First identified in 1967, lonsdaleite is the hardest naturally-occuring mineral ever discovered—yes, it’s even harder than diamonds. Lonsdaleite, however, has only been found in meteorites, suggesting ...

New research indicates that a rare form of diamond may originate in the burbling cores of distant worlds, arriving on Earth thanks to violent cosmic collisions. According to a team of scientists in ...

In the case of lonsdaleite [hexagonla diamond], compression mechanism also caused bond-flipping, yielding an indentation strength of 152 GPa, which is 58 percent higher than the corresponding value of ...

Australian scientists have discovered strangely folded diamonds in rare meteorite samples. In investigating how they came to form, the team found evidence that they were forged in a cataclysm on an ...

A collection of 18 rare diamond-bearing meteorites from around the world came from an ancient dwarf planet that smashed into a giant asteroid 4.5 billion years ago, according to new research. The ...

The mystery of the diamond-containing meteorites found across the world has finally been solved. Scientists from RMIT and Monash University in Australia have discovered that the diamonds were formed ...
