Natural Peridot Crystal with Ludwigite Inclusions - Rare Specimen from Supat Mine, Pakistan

Diamonds reveal hidden chemistry deep inside Earth

Diamonds from South Africa's Voorspoed mine have revealed the first natural evidence of nickel-rich metallic alloys forming deep in Earth's mantle, between 280-470 km (174-292 miles). A new study reveals that these inclusions coexist with nickel-rich carbonates, capturing a rare snapshot of a "redox-freezing" reaction whereby oxidized melts infiltrate reduced mantle rock. The growing diamond trapped both reactants and products of a diamond-forming reaction. This finding not only confirms long-standing predictions about mantle redox conditions but also highlights how such processes may fuel diamond formation of volatile-rich magmas that erupt from hundreds of kilometers and bring the diamond to the surface. The Earth's mantle is a restless, enigmatic engine that powers volcanism, recycles crust, and regulates the long-term evolution of the planet. But one of its most elusive characteristics -- the redox state, or the balance of oxidized and reduced chemical species -- remains difficult to measure directly. A new study led by Yael Kempe and Yaakov Weiss, from the Hebrew University's Institute of Earth Sciences, offers a rare glimpse into these deep processes, captured within nano- and micro-inclusions in diamonds from South Africa's Voorspoed mine.
