The Okavango Blue Diamond, a dazzling 20.46-carat stone, is more than just a beautiful jewel-it's practically a miracle of nature. Unearthed from the Orapa mine in Botswana, this rare gem has ...

The high-pressure, high-temperature technique created tiny disks of this ultrahard diamond which could ultimately replace conventional diamonds in applications such as drilling tools and electronics, ...

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 ...

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

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

Scientists have created the first sizable sample of hexagonal meteorite diamond which is predicted to be harder than conventional diamonds.

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.

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?
