☆ Australia's rare pink-diamond mine formed from the clashing and stretching of continents, a new study found. The discovery could lead to more colorful diamonds.

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. Turns out, pink diamonds form under even more intense conditions than traditional clear diamonds. Though pink diamonds have been found in Angola and India, Argyle was by far the most prolific site — 90% of the world's pink diamonds came from it. After all, there is financial incentive behind finding a second Argyle — pink diamonds have sold for as much as $71 million dollars, according to Forbes.

☆ Fountains of diamonds erupt from the ground when continents break up, say scientists — and it could help uncover new deposits

These eruptions have baffled scientists as they happen more often after continents break up. "The pattern of diamond eruptions is cyclical, mimicking the rhythm of the supercontinents, which assemble and break up in a repeated pattern over time," Gernon said. In fact, scientists found that most kimberlite volcanoes occurred 20 to 30 million years after the tectonic breakup of Earth's continents. But instead, it tends to appear in "a sweet spot in the interior of continents where diamonds form," Gernon said. Sergei Karpukhin/ReutersThe scientists say having uncovered this chain reaction could help discover diamond deposits in the future.

☆ When Ancient Eruptions Pumped Diamonds to Earth’s Surface

While diamonds might look pretty perched atop a ring, the rocks they hail from venture to Earth’s surface in a journey that’s anything but glamorous. Millions of years ago, some of our planet’s strangest and most violent volcanic outbursts dredged from deep underground most of the diamonds mined today in the form of blue-tinged rocks called kimberlites. The turbulent flow punches a carrot-shaped pipe through the ground, ripping out chunks of deep subsurface rock, including some that are studded with diamonds. A new study led by Dr. Gernon and published Wednesday in the journal Nature points to the ancient roots of these eruptions. He and his colleagues report that the breakup of ancient supercontinents like Pangaea and Rodinia caused deep disruptions in the flow of the mantle beneath Earth’s crust, setting off the blasts.
