Most natural diamonds have ages between 1 billion and 3.5 billion years. Diamond is the only gem with a single element. Do ...

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 ...

A nitrogen-vacancy (NV) center is a flaw in the diamond crystal structure that occurs when an adjacent lattice site becomes unoccupied and a nitrogen atom takes the place of a carbon atom. Researchers ...
