"Revealing the Enigma: Unraveling Earth's Deepest Gemstone"

Scientists from Curtin University have discovered the missing ingredient in the formation of pink diamonds by studying the Argyle volcano in Western Australia. In addition to deep carbon and tectonic plate collisions, the stretching of continents during continental break-ups creates pathways for diamond-bearing magma to rise to the Earth's surface. The researchers found that the stretching of landmasses created gaps in the Earth's crust, allowing diamond-carrying magma to emerge. This discovery could aid in the search for new pink diamond deposits worldwide. The Argyle volcano, which has produced over 90% of the world's pink diamonds, is situated at the suture of two ancient continents, making it a unique source of these rare gems.

The Origins of Rare Pink Diamonds Revealed: A Supercontinent's Breakup

Scientists have discovered that pink diamonds, known for their extreme rarity and high value, may have formed when an ancient supercontinent called Nuna broke up billions of years ago. Using narrow laser beams and mass spectrometry, researchers determined that pink diamonds from the Argyle diamond deposit in Western Australia are approximately 1.3 billion years old, 100 million years older than previously estimated. The study suggests that the movement of colliding crusts during the breakup of Nuna caused these rare diamonds to rise to the surface. The findings also indicate the possibility of undiscovered pink diamond deposits buried under layers of rock and sediment.

Uncovering Clues to Rare Pink Diamonds: From Supercontinent Breakups to Volcanic Revelations

Researchers studying the Argyle diamond deposit in Western Australia have gained a better understanding of the geological conditions necessary for the formation of pink diamonds. Using lasers to analyze minerals and rocks, they discovered that the pink diamond-rich site formed during the breakup of an ancient supercontinent called Nuna, around 1.3 billion years ago. The study suggests that the junctures of ancient continents may be important for finding pink diamonds and could guide exploration for other deposits.

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.
