After decades of debate, researchers say that they have found the clearest evidence yet for this rare form of carbon ...

Scientists create first-of-its-kind ‘hexagonal diamond’ harder than real thing - Material exhibits slightly higher hardness than naturally found diamond ...

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.

Carbon comes in many different structures, most famously graphite and diamond. Other forms were predicted to exist at extremely high pressures, but now researchers have examined carbon under the ...

A study on the diamonds titled "Sequential Lonsdaleite to Diamond Formation in Ureilite Meteorites via Chemical Fluid/Vapor Deposition" has been published in the journal Proceedings of the National ...

Diamonds created by an interstellar collision of a dwarf planet and an asteroid could lead to the development of new super-hard materials for tools and production, researchers say. Rare lonsdaleite ...
