By Danny Shea


Most people believed that the famous Kohinoor and the blue Hope diamond were discovered in the Middle Ages. In the 14th century in India, the diamond polishing was first recorded by the Europeans. By this moment, the real face of the diamond was not completely discovered. In the 16th century the first diamond cutting was started.

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.

There are about fifty percent of diamonds found in the central and southern Africa. There are also some valuable sources in other countries, such as India, Russia, Brazil, and Australia. 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.

Mines found in the countries of central and southern Africa are the modern source for the majority of diamonds. 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.
