A pair of diamonds that formed hundreds of kilometers deep in Earth’s malleable mantle both contain specks of materials that form in completely opposing chemical environments—a combination so unusual ...

The discovery of two diamonds originating from the depths of the Earth's mantle reveals a chemical coexistence that ...

Seemingly contradictory materials are trapped together in two glittering diamonds from South Africa, shedding light on how ...

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 ...

Two diamonds from South Africa’s Voorspoed mine provide a rare direct insight into the chemistry of Earth’s mantle. Although ...

Synthetic diamond research examines organic molecular interactions under the microscope. Scientists have long developed different techniques to produce artificial diamonds, but a new method from ...

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 ...

A study found that Australia's tectonic plates stretched, creating large deposits of pink diamonds. Pink diamonds are made under extreme pressure when two continents collide. The scientists hope that ...

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, ...

A French tourist accidentally finds a 7.46-carat diamond at the Crater of Diamonds (Arkansas) on January 11, 2024, public.
