Kimberlite is a relatively rare type of lava. It comes from depths as great as 300 to 350 kilometers. On its way to the surface, kimberlite frequently picks up rock and mineral fragments, including diamonds, one of which can be seen in this sample. In fact, kimberlite is the main source of diamonds. Diamonds are the deepest-known objects from the Earth’s interior.
