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.
