Together with an international team of researchers, they have now been able to prove that these diamonds formed in the early period of our solar system when minor planets collided together or with large asteroids. These new data disprove the theory that they originated deep inside planets - similar to diamonds formed on Earth - at least the size of Mercury (PNAS). (2020-09-29)
