Physicists have successfully created a lab-grown diamond with a hardness exceeding that of natural diamonds. By subjecting ...

Diamond is well-known for being the hardest natural material on Earth, though synthetic forms have been developed that are even tougher – a feat that researchers have managed again, through a new ...

In 1967, a hexagonal form of diamond, later named lonsdaleite, was identified for the first time inside fragments of the Canyon Diablo meteorite, the asteroid that created the Barringer Crater in ...

In brief: Chinese researchers have developed a synthetic diamond that is significantly harder and more resilient than those that occur naturally here on Earth. If commercially viable, the new diamond ...

Chinese scientists have created an artificial “super diamond” much greater in hardness than real ones, an advance that could lead to breakthroughs across several key industries that rely on the ...

Scientists have created the first sizable meteorite diamond — also known as lonsdaleite or hexagonal diamond — a material predicted to be even harder than the diamonds normally found on Earth. The ...
