A pair of diamonds that formed hundreds of kilometers deep in Earth’s malleable mantle both contain specks of materials that ...

Synthetic diamond research examines organic molecular interactions under the microscope. Scientists have long developed ...

A new process of diamond formation has been theorized that could indicate they are more plentiful than thought. It involves the acidification of water at great depths, producing minuscule diamonds in ...

The graphite found in your favorite pencil could have instead been the diamond your mother always wears. What made the difference? Researchers are finding out. How molten carbon crystallizes into ...

These diamonds acted as “tiny time capsules,” preserving a rare snapshot of deep Earth processes. “This is a rare snapshot of mantle chemistry in action,” said Yaakov Weiss, the study’s lead author.
