“These findings resolve the long-standing controversy on the existence of hexagonal diamond,” researchers said.

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 ...

After decades of chasing after a rare hexagonal diamond, a Chinese team says their iteration of the elusive material is the ...

The diamond was around 0.04 inches in size and exhibited more sturdiness and resistance compared to typical cubic 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 ...

A team of researchers has reported the first laboratory synthesis and recovery of bulk hexagonal diamond, a crystal form long predicted to be harder than the conventional gems used in cutting tools ...

Scientists found something unexpected inside a meteorite that hit Earth 50,000 years ago. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. While ...

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 ...
