Diamond is famously known as the hardest mineral on Earth. “There are hundreds of claims from people who believe they have seen it,” says Oliver Tschauner, a mineralogical crystallographer at the ...

Molten carbon can form into either diamond or graphite. A new study shows how graphite can sometimes form even under conditions that should lead to diamond. (Getty Images) The graphite found in your ...

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 ...

A new technique uses a pulsing laser to create synthetic nanodiamond films and patterns from graphite, with potential applications from biosensors to computer chips. “The biggest advantage is that you ...
