Physicists have successfully created a lab-grown diamond with a hardness exceeding that of natural diamonds. By subjecting graphite to extreme pressure and heat, researchers synthesized a rare ...

through a new approach to diamond formation. The team put graphite (another super-hard material) under an intense amount of pressure, before heating it to 1,800 K (that's 1,527 °C or 2,780 °F).

It is an open-pit mine, formed around a rare volcanic rock formation called a kimberlite pipe, which contains high ...

The effort is part of a project to reconfigure the I-75 interchange at U.S. 301 to a tight diamond formation, and replace the ramps across the Manatee River. The interchange is expected to be ...

Scientists say this study provides insights into diamond formation. The method could help create ultra-hard materials for various uses. Previous attempts to make hexagonal diamonds have seen ...
