Lonsdaleite was found in so-called “ureilite meteorites”, an unusual type of stony space rock believed to have originated in the mantle of a destroyed inner solar system dwarf planet. Ureilites tend ...

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 ...

A “folded diamond” doesn’t sound entirely plausible. But that’s exactly what we’ve found inside a rare group of meteorites known as ureilites, which likely came from the mantle of a dwarf planet or ...

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 ...

Chinese scientists have synthesized a "super diamond" that is 40 percent harder than natural diamonds and exhibits high thermal stability, a breakthrough that could enhance the performance of ...
