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 ...

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 ...
