Web a mined, natural diamond is a crystallized carbon structure that is formed beneath the earth’s surface over millions (or sometimes billions) of years under the perfect conditions of heat and pressure. Web most were formed at depths between 150 and 250 kilometres (93 and 155 mi) in the earth's mantle, although a few have come from as deep as 800 kilometres (500 mi). Web diamonds are formed deep within the earth: But the real story is far more. Web diamonds are not only formed under the heat and pressure of the earth’s gravity, but can form in the midst of a collision between earth and an asteroid. The pipes themselves are often less than 100 million years old. These conditions are only achieved deep within the earth. Each natural diamond is made of pure carbon, compressed by earth’s pressure over time, and is the hardest substance on earth that exists naturally. Obviously in that part of the earth it's very hot. Web deep inside the atmospheres of the ice giants neptune and uranus, carbon can be compressed to the extreme pressures and temperatures needed to form diamonds, according to space.com.
Diamonds are found at a depth of approx. The gems are brought to the surface of the earth during a seismic event like a volcanic eruption, embedded in large chunks of rocks called xenoliths. Web diamonds are formed deep within the earth about 100 miles or so below the surface in the upper mantle. Web thus, diamond can potentially form in any region of the earth where the depth of the crust or the mantle provides high enough pressure, because the temperature will also be high enough. Learn about the discovery and the evolution of the modern diamond industry and gia can determine a diamond’s country of origin. Obviously in that part of the earth it's very hot. A pervasive myth about how natural diamonds are formed is that they come from buried coal, squeezed at high pressures. Web diamonds are formed deep within the earth: Between 100 km and 200 km below the surface. Web coal could be present in the target area of these impacts and could serve as the carbon source of the diamonds. Web diamonds are not only formed under the heat and pressure of the earth’s gravity, but can form in the midst of a collision between earth and an asteroid.
