A Chinese research team has produced bulk hexagonal diamond, a crystal structure long theorized to be harder than ...

Researchers have synthesized millimetre-scale hexagonal diamond, a crystal structure so elusive that many physicists doubted ...

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 ...

Scientists created a pure hexagonal diamond in the lab, confirming a long-debated carbon structure slightly harder than natural diamonds.

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 ...

Pressure makes diamonds, but according to recent findings, there may also be a much quicker, hassle-free way. A team of researchers at Stanford University has stumbled upon a new way of turning ...
