Scientists have debated its existence. Tiny traces provided clues. Now, researchers have confirmed the existence of a celestial diamond after finding it on Earth’s surface. 

The stone, called lonsdaleite, has a hardness and strength that exceeds that of a regular diamond. The rare mineral arrived here by way of a meteorite, new research has suggested.

What’s more, the natural chemical process through which scientists believe lonsdaleite formed could inspire a way to manufacture super-durable industrial components, according to the authors of the study published September 12 in the journal Proceedings of the National Academy of Sciences.

The revelation started to unfold when geologist Andy Tomkins, a professor at Monash University in Australia, was out in the field categorizing meteorites. He came across a strange “bended” kind of diamond in a space rock in Northwest Africa, said study coauthor Alan Salek, a doctoral student and researcher at RMIT University in Australia.

Tomkins theorized the meteorite that held the lonsdaleite came from the mantle of a dwarf planet that existed about 4.5 billion years, Salek said.

“The dwarf planet was then catastrophically struck by an asteroid, releasing pressure and …
