Radioactive diamond batteries were first developed in 2016 and promised a new, cost-effective way of recycling nuclear waste.

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

Nuclear power is considered a clean energy source because it has zero carbon dioxide emissions; yet, it produces massive amount of waste.

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.
