In adamantane, the carbon atoms are in the right diamond-like arrangement, but each carbon is capped with hydrogen atoms. As ...

Rare diamonds found in meteorites called ureilites have a folded hexagonal structure. Learning the process of how they were formed could inspire better lab-grown diamonds.

This new study found that pink diamonds generally are found in locations where the Earth’s continents were ‘stretched’ when they began to break up hundreds of millions of years ago.

Formed millions to billions of years ago, diamonds can shine light into the darkest and oldest parts of the Earth's mantle. The analysis of ancient, superdeep diamonds dug up from mines in Brazil ...

Chemical analyses of the rarest diamonds suggest the planet’s carbon cycle may not go as deep as scientists thought.
