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.
