In 1823 the Scottish scientist Sir David Brewster, known at that time for his famed optical experiments, (and inventing the kaleidoscope), described a “remarkable new liquid found trapped inside cavities of crystals” and dutifully reported what he had discovered in the Transactions of the Royal Society of Edinburgh science journal.

New mineral from Earth’s lower mantle surfaced as diamond inclusion; study led by UNLV geochemist Oliver Tschauner.

UNLV geochemists have discovered a new mineral on the surface of the Earth. But they say it shouldn’t be here.

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.

Scientists have discovered for the first time a new mineral encased within a diamond from over 600km deep within the Earth’s lower mantle, which they say should’ve fallen apart before reaching the surface.

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.
