New Study Reveals Deep Mantle Origins of the World’s Rarest Diamonds
Scientists Trace Origin of Rare CLIPPIR Diamonds to Iron-Rich Mantle Zones Deep Beneath Earth’s Surface The formation of the world’s rarest and most valuable gem-quality diamonds known as CLIPPIR diamonds (Cullinan-like, large, inclusion-poor, pure, irregular and resorbed) has long puzzled scientists. A new study led by University of Cape Town (UCT) now provides critical insights into their origin deep within the Earth’s mantle. Conducted by the Kimberlite Research Group (KRG) in the Department of Geological
