There are various ways to create artificial diamonds, but a new method developed by researchers, including those at the ...

Diamonds are made out of carbon — highly organized carbon, that is. Geologists are still guessing how diamonds formed in the ...

Eclogitic diamonds formed in Earth's mantle originate from oceanic crust, rather than marine sediments as commonly thought, according to a new study from University of Alberta geologists.

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 ...

A team of Chinese scientists may have cracked the secret behind the strange Canyon Diablo diamonds. Hexagonal in form rather than cubic, the process behind how these diamonds formed has, until now ...

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 ...

This new study found that pink diamonds generally are found in locations where the Earth’s continents were ‘stretched’ when they began to break up hundreds of millions of years ago.

Chemical analyses of the rarest diamonds suggest the planet’s carbon cycle may not go as deep as scientists thought.

Pink diamonds are extremely rare and coveted. But a discovery made in Western Australia near a now-closed mine may help reveal new deposits of the jewels, researchers say.
