Diamonds are famously formed under high pressure and temperature, which is partly why they’re so valuable. But now, scientists have created diamonds in a lab under regular pressure in just 15 minutes.

Carbon comes in many different structures, most famously graphite and diamond. Other forms were predicted to exist at extremely high pressures, but now researchers have examined carbon under 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 ...
