This goes hard.
Diamonds are forever, and they're also everywhere: in exoplanets, in meteorites, in your mother’s wedding ring. Some, though, are far more exotic than what you'd find in your local mall’s Swarovski., a team of researchers say they’ve found the largest crystals yet of a mysterious form of diamond called lonsdaleite.
. And because it doesn’t form naturally on Earth, lonsdaleite has only been found in rare ureilite meteorites, making it a tough task to uncover the material’s origins."This study proves categorically that lonsdaleite exists in nature," said senior researcher Dougal McCulloch from RMIT, in aMcCulloch and company’s findings also uncovered that these instances of lonsdaleite may have been formed in the wake of a dwarf planet smashed by a gigantic asteroid about 4.5 billion years ago.
"There’s strong evidence that there’s a newly discovered formation process for the lonsdaleite and regular diamond," said McCulloch, "which is like a supercritical chemical vapor deposition process that has taken place in these space rocks, probably in the dwarf planet shortly after a catastrophic collision.
In fact, lead author of the study and Monash University geologist Andy Tomkins believes the findings could help replicate the process artificially on an industrial scale, where the extraordinarily tough diamonds could then be used to create "ultra-hard machine parts." Lonsdaleite hasRegardless of industrial feasibility, finding mysterious diamonds from an ill-fated planet? That's pretty gnarly.
