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 ...

Forbes contributors publish independent expert analyses and insights. David Bressan is a geologist who covers curiosities about Earth. Over 70 percent of the world’s diamonds are mined from kimberlite ...

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 ...

“A diamond is forever.” That iconic slogan, coined for a highly successful advertising campaign in the 1940s, sold the gemstones as a symbol of eternal commitment and unity. But our new research, ...
