A pair of diamonds that formed hundreds of kilometers deep in Earth’s malleable mantle both contain specks of materials that form in completely opposing chemical environments—a combination so unusual ...
Researchers have succeeded in creating a rare type of diamond, known as lonsdaleite or hexagonal diamond. This material, whose hardness could surpass that of conventional diamonds, opens new ...

Scientists report a harder diamond form, reviving a long-running debate
A team of researchers has reported the first laboratory synthesis and recovery of bulk hexagonal diamond, a crystal form long predicted to be harder than the conventional gems used in cutting tools ...
It takes intense pressure and temperatures north of 2,000 degrees for a diamond to form deep within the Earth. But these days, there’s another way to create a diamond: in a lab, where a diamond can go ...
A study found that Australia's tectonic plates stretched, creating large deposits of pink diamonds. Pink diamonds are made under extreme pressure when two continents collide. The scientists hope that ...
