Surprisingly we do not have much information about the center of the planet that we live on. What lies beneath our feet is not well known.

Strange diamonds from an ancient dwarf planet in our solar system may have formed shortly after the dwarf planet collided with an asteroid.

Researchers at SLAC found that oxygen boosts this exotic precipitation, revealing a new path to make nanodiamonds here on Earth.

Today, it’s difficult to engineer resilient and long-lasting components that can control the powerful beams that lasers emit.

Traditional diamond mining is fraught with problems, from worker exploitation to deforestation and water pollution.

A startup called Aether is turning CO2 from the atmosphere into something new: the world’s first carbon-negative diamonds.

As hard as diamond and as flexible as plastic, highly sought-after diamond nanothreads would be poised to revolutionize our world.

Flaws in diamonds — atomic defects where carbon is replaced by nitrogen or another element — may offer an interface for quantum computing.

A California couple visited a state park in Arkansas and made an amazing discovery -- a massive 4.38-carat diamond.

There might be a quadrillion tons of diamonds 100 miles below Earth’s surface. But the farthest we’ve traveled is 7 miles down.

As missions like NASA’s Hubble Space Telescope, TESS and Kepler continue to provide insights into the properties of exoplanets

A Washington man found a two-carat diamond during his third day hunting for them at Crater of Diamonds State Park

On the rooftop of a power-generating waste plant near Zurich, Switzerland, a row of large machines pulls carbon dioxide from the air.
