Unveiling the Origins of Earth's Rare Pink Diamonds

Australian researchers have discovered that pink diamonds, which are among the rarest and most valuable diamonds, may have emerged from deep underground during the breakup of the supercontinent Nuna around 1.3 billion years ago. The diamonds formed near the stable continental roots and were pushed to the surface during the collisions that occurred during the breakup of Nuna. The findings suggest that ancient continental junctures may hold more of these colorful gems, shedding light on the geological processes that create pink diamonds. However, questions remain about the abundance of carbon that led to the formation of the Argyle mine's diamonds.
