History Black diamonds are the rarest in the diamond family. Also called carbonado, black diamonds were created 3.5 billion years ago. Over time, they pushed their way up to the surface through volcanic eruptions about 1 million years ago. Black diamonds are considered to be "young," as clear diamonds were formed approximately 4.25 billion years ago.
People are really aware of the diamond from this century, and started economically mining. They noticed that the diamond could be found in the Earth's oldest continental state, which was called cartons. These cartons were consisting of inactive environmental area deeply under the earth, and it was more than two thousand years old. The diamond was formed and preserved in this carton. Some diamonds can be determined the ages by dating mineral impurities. Some of them are disclosed that there has been three thousand years ago.

Some diamonds can be found in the crystals from deep in the Earth, where the kimberlitic are and lamppost volcanic pipes. These places are high pressure and temperature, which is the formation of the crystals.

However there are other regions where diamonds are still mined including Brazil, Australia, Canada, and Siberia. In fact, Siberia enjoys the reputation of having the world's largest diamond mine.
