Diamonds Are Found In Which Type Of Rock. Diamonds are the hardest natural substances on the planet. This rock is found in a type of igneous rock known as kimberlite. The diamond is essentially a chain of carbon atoms that has crystallized into a diamond. Because of the denseness of the carbon chains, the hardness of a stone is unique.However, the source rocks of diamonds are vertical pipes filled with igneous rocks. Four processes are thought to be responsible for virtually all of the natural diamonds that have been found at or near Earth's surface. One of these processes accounts for nearly 100% of all diamonds that have ever been mined. Dolostone is a very tough rock, so expect to work hard. At locations where "Herkimer diamonds" are found, the dolostone is usually heavily silicified. This significantly increases the hardness and toughness of the rock. The use of safety glasses is required, and a pair of goggles is even better.
