Over time, glaciations, earth movement and volcanic activity may have broken and scattered the pipes, but they are not lost to diamond miners.
Diamonds of value do not form within Earth’s magma, but rather deeper in the earth under greater pressure. However, diamonds do form in mineral crystal deposits found in igneous rock. This rock is in the upper mantle of the Earth’s crust, and crystallizes with the help of minerals known as peridotites and eclogites under specific temperature and pressure conditions.
Diamonds are most abundant in stable layers of the Earth’s crust called cratons, and are usually found in cratons that are at least 570 million years old.
