Rocks that contain diamonds.

Diamonds, an occasional component of rare igneous rocks called lamproites and kimberlites, have never been dated satisfactorily. However, some diamonds contain minute inclusions of silicate minerals, commonly olivine, pyroxene, and garnet. Kimberlite pipes bring the gems to the surface in eruptions that sometimes rise faster than the speed of sound. The pipes are rare.

Herkimer Diamonds are doubly-terminated quartz crystals mined in New York. Diamond is much more than the world’s most popular gemstone and hardest natural material. Today man-made diamonds are being used in computers, speakers, cutting tools, bearings, laser windows, wear-resistant parts and much more.

Eclogite, a very different rock, consists of garnet and sodium-rich pyroxene; some also contains diamonds. Diamond inclusions Diamonds with inclusions are like little space capsules from the mantle: pristine mineral samples are protected by the diamond's indomitable embrace and transported to the surface by a volcanic rocket.The first step is to find a likely looking rock that could contain diamonds. Next, break the rock open with a hammer and look for shiny, well-formed crystals. If the crystals are small and included in the rock, it is known as an indicator mineral. If you find an indicator mineral, there is a good chance that there are diamonds nearby.

Herkimer diamond in a vug: A vug is an unlined cavity that will not remain when the rock that contains it weathers away. The famous doubly-terminated quartz crystals known as "Herkimer Diamonds" occur within vugs in the Little Falls Dolostone of Herkimer County, New York. The rock in the photo is about 18 centimeters across.Diamond still inside!

The most common way to find diamonds is through kimberlite pipes. Kimberlite is a type of igneous rock that is found in many parts of the world. These pipes are formed when magma rises to the surface and then cools. The magma contains a lot of diamonds, which are then carried to the surface by the kimberlite.kimberlite, also called blue ground, a dark-coloured, heavy, often altered and brecciated (fragmented), intrusive igneous rock that contains diamonds in its rock matrix. It has a porphyritic texture, with large, often rounded crystals (phenocrysts) surrounded by a fine-grained matrix (groundmass).But it still is a great question. Well, the answer is yes! But it can’t be any type of lava – which means that it can’t be any type of rock, either. To be precise, there is only one rock that we managed to find that can both contain diamonds and melt into lava and end up on the surface. That rock is called a kimberlite.

Some South African mines operate at 25 carats of diamond per 100 cubic meters of rock or about 2 grams of diamonds per 100 tons of rock. Because diamond has a specific gravity of 3.5 grams per cubic centimeter, 1 cubic centimeter of diamond weighs 16 carats. These diamonds are rare and make up a minor portion of worldwide diamond production. Gemstone diamonds are sold for their beauty and quality. Natural diamond crystals have a specific gravity that ranges between approximately 3.4 to 3.6. This range exists because most diamonds contain impurities and have irregularities in their crystal structure.In fact, most igneous and metamorphic rocks contain oxide minerals.
