Researchers have succeeded in creating a rare type of diamond, known as lonsdaleite or hexagonal diamond. This material, ...

In nature, diamonds form in geologic crucibles where pressure can be 50,000 times higher than at sea level. Temperatures soar to over 1,500˚C.

In nature, diamonds form deep in the Earth over billions of years. This process requires environments with exceptionally high pressure and temperatures exceeding 1,000℃. Our international team ...

Meteorite diamonds, which could be 58% harder than ordinary diamonds, have finally been made in the lab. Scientists have ...

Researchers have previously pursued harder diamonds with hexagonal rather than cubic lattices, which is how most natural and synthetic diamonds form.

The vast majority of polished diamonds are clear and sparkly, but some come in unexpected colors like blue, green and even pink. So why are some diamonds different colors?

Researchers at The City College of New York have shown how a quantum emitter, the nitrogen-vacancy (NV) center in diamond, ...

There's a reason why engagement rings are more expensive than wooden pencils. Diamond and graphite are both made of ...

Cracking the secret of meteorite diamonds Deep inside Earth, diamonds form about 90 miles below the surface where temperatures exceed 2,000 degrees Fahrenheit.

New research suggests the presence of a diamond layer in Mercury's core, challenging previous assumptions about the planet's composition and potentially explaining its strong magnetic field.
