Tiny flaws in diamonds hold the secret to the formation of the first continents. In a new study, researchers used inclusions — imperfections derided by jewelers but valuable to scientists — to trace ...

Diamonds form deep within the Earth's mantle, around 250 kilometers below the surface, where immense pressure (up to 10 GPa) and temperatures (around 2,200 °C) compress carbon into diamonds over ...

Diamonds in nature famously form under immense pressure in Earth’s mantle. But a new laboratory technique allows diamonds to skip the squeeze. The most common method for producing synthetic diamonds, ...

In nature, diamonds form deep in the Earth over billions of years. This process requires environments with exceptionally high pressure and temperatures exceeding 1,000℃. Our international team has ...

The world’s largest source of natural diamonds — and of more than 90 percent of all natural pink diamonds found so far — may have formed due to the breakup of Earth’s first supercontinent, researchers ...
