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 ...

Scientists have finally made an elusive meteorite diamond, predicted to be 50% harder than Earth diamonds
Scientists have created the first sizable meteorite diamond — also known as lonsdaleite or hexagonal diamond — a material predicted to be even harder than the diamonds normally found on Earth. The ...
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 ...
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 ...
