UNLV geochemists have discovered a new mineral on the surface of the Earth. There’s just one catch: it shouldn’t be here.

‘Davemaoite’ usually only exists in the deep Earth. Plus, homicide is a top cause of maternal death in the United States, and what scientists think of the Glasgow Climate Pact.

Newly discovered mineral, named davemaoite, was found encased within a diamond.

Researchers thought the mineral was impossible to find on Earth's surface.

The rare mineral, long hypothesized but never seen, was recovered from a diamond that emerged from the Earth's lower mantle.

Scientists thought they might never find a sample of the elusive mineral.

In a major discovery, mineralogists identified a new mineral in a diamond mined from about 410 miles (660 km) below the surface of the earth in Botswana.

A group of scientists recently discovered a mineral inside a diamond taken from the depths of the earth for the first time.

Scientists have discovered the first instance of a never-before-seen mineral inside a diamond pulled from deep down the Earth's surface.

This mineral, that can only form under high pressure and high temperatures in Earth's mantle, was never seen before until scientists discovered a sample of it trapped in a diamond.

A diamond discovered deep beneath Earth’s surface contains a mineral that has never been found before on our planet.

Ancient diamond boulderfrom Botswana has black spots which are apparently a type of mineral that has never been seen before. The mineral, called davemaoite, is a unique window for scientists to see rock chemistry from the depths of the Earth.
