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.
“Nature has thus provided us with a process to try and replicate in industry,” Tomkins said in a news release. “We think that lonsdaleite could be used to make tiny, ultra-hard machine parts if we can develop an industrial process that promotes replacement of pre-shaped graphite parts by lonsdaleite.” What is it exactly? Long before this discovery, scientists have debated the existence of lonsdaleite, Asimow said.
