The amount of nickel - 60 found in meteorite samples — particularly in comparison to the amount of stable, «ordinary» iron - 56 — can indicate how much iron - 60 was present when the larger parent body from which the meteorite broke off was formed.
These crashes were big and energetic and, in the case of the diamond - laden meteorite's parent body, caused catastrophic disruptions that the crystals captured.
Current thinking is that these tiny diamonds can form in three ways: enormous pressure shockwaves from high - energy collisions between the meteorite «parent body» and other space objects; deposition by chemical vapor; or, finally, the «normal» static pressure inside the parent body, like most diamonds on Earth.
