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, ...

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

Recent astronomical discoveries have captivated the world with the revelation of a planet composed entirely of diamonds. This ...

They don’t make them like they used to — at all. It can take natural diamonds over three billion years to grow, but researchers in a South Korean lab have successfully fabricated the precious stones ...

Diamonds aren't always colorless; they can also be blue, yellow, green and even pink. But what makes these jewels come in varied hues? After forming, diamonds need to rise to the surface very quickly ...

It’s raining diamonds! Well, it’s raining diamonds on other planets at least, including some in our Solar System. And scientists recently discovered that the conditions needed to create this wild ...

Meteorite diamonds, which could be 58% harder than ordinary diamonds, have finally been made in the lab. Scientists have ...

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 ...
