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

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 ...

Diamonds are famous for their strength, but scientists have long suspected that another form of diamond might be even harder.

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

Researchers made small, pure samples of the elusive mineral lonsdaleite – also known as hexagonal diamond — and tested its ...

Chinese scientists claim to have created the long theorised hexagonal diamond, stronger than the real thing, and only found ...

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 treasure trove of diamonds may be sown into Mercury’s cratered crust. Billions of years of meteorite impacts may have flash-baked much of Mercury’s surface into the glittery gemstones, planetary ...

Molten carbon can crystallize into diamond or graphite, but it has been difficult to study this process. New simulations show that graphite can sometimes "hijack" the pathway that would lead to ...
