Did you know? Diamonds were first uncovered
W ithin a diamond hauled from deep beneath Earth’s surface, scientists have discovered the first example of a never-before-seen mineral. Named davemaoite after prominent geophysicist Ho-kwang (Dave) Mao, the mineral is the first example of a high-pressure calcium silicate perovskite (CaSiO 3 ) found on Earth. Another form of CaSiO 3 ,known as wollastonite, is commonly found across the globe, but davemaoite has a crystalline structure that forms only under high pressures and temperatures in Earth’s mantle, the mainly solid layer of Earth trapped between the outer core and the crust. in India
