Diamonds are famous for their strength, but scientists have long suspected that another form of diamond might be even harder. Evidence of this was gathered over the past sixty years in meteorite ...

A new form of diamond has been created. Its unique structure gives it properties that are similar to those of natural diamonds, but it is more stable under extreme heat, so may be useful in tools that ...

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

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

New research indicates that a rare form of diamond may originate in the burbling cores of distant worlds, arriving on Earth thanks to violent cosmic collisions. According to a team of scientists in ...

Diamond stands up to a squeeze. Surprisingly, the material’s structure persists even when compressed to 2 trillion pascals, more than five times the pressure in Earth’s core, scientists report January ...

Even with the weight of worlds on its shoulders, diamond resolutely refuses to buckle under the pressure. Thanks to the highest-pressure X-ray diffraction experiments ever reported, researchers have ...

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

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 ...

The mantle has three to five times more carbon than researchers would expect based on the proportion of elements in stars and other planets. The diamonds found in this layer of Earth might explain the ...

The team found that the distance between the graphene layers is unusual due to the unique environments of carbon atoms occurring at the interface between diamond and graphene. They also demonstrated ...
