A rare two-coloured diamond has been discovered in Botswana, in southern Africa. The rough stone is half-pink and ...

Molten carbon can crystallize into diamond or graphite, but it has been difficult to study this process. New simulations show that graphite can sometimes "hijack" the pathway that would lead to ...

Diamond is well-known for being the hardest natural material on Earth, though synthetic forms have been developed that are even tougher – a feat that researchers have managed again, through a new ...

There are various ways to create artificial diamonds, but a new method developed by researchers, including those at the University of Tokyo, yields some extra benefits. Subscribe to our newsletter for ...

Paving the way to a dry process with less environmental impact Tools coated with diamond film (diamond-coated tools) are used for difficult-to-machine materials such as CFRP. In the manufacture of ...

Almost 100 million years ago, in what is now Pike County, nature created one of the world's most unusual diamond-bearing formations, the big volcanic "pipe" that now serves as the centerpiece of ...

The graphite found in your favorite pencil could have instead been the diamond your mother always wears. What made the difference? Researchers are finding out. How molten carbon crystallizes into ...
