How Are Diamonds Formed

The history of diamonds is one of supernatural power, beauty and marketable expertise, from legends about valleys of diamonds secluded by snakes, to the construction of millions of carats in coarse diamonds each year.

A Diamond is formed when intense force and tremendous heat cause carbon atoms to crystallize forming diamonds just about ninety miles underneath the earth's surface. These precious stone get in touch with the earth’s surface through volcanic pipes or via placer / alluvial deposits. Kimberlite is a blue rock that occurs in earliest volcanic pipes and is the most common host of diamonds. When a volcano erupts, diamonds are also dumped on, or near, the surface. Some of the kimberlite host rock is washed away by streams and rivers and diamonds are deposited as residue in the stream or sands in alluvial deposits which are also called as the placer deposits. These deposits are caused by volcanic eruptions or by millions of years of erosion caused by melting snow and rainfall which reveal the diamonds from their kimberlite supply.

A diamond is one of the earth's most common elements. It is a transparent gem made of carbon. The configuration of diamonds began very early in the earth's history, when the compression of solid matter into a sphere caused the centre of the planet to become subjected to far-fetched extremes of temperatures and pressure. It was these very circumstances that caused deposits of carbon to begin to crystallize deep in the earth. Volcanic activity forced streams of magna (liquid rock) to the surface, as the earth's surface cooled carrying with it the diamond crystals. Later on, the diamond-bearing rock hardened, enclosing the diamonds in vertical volcanic "pipes".

However, not all diamonds are being brought as they first came to the surface. Consequent erosion of the topsoil over millions of years had spread some of the diamonds into streams and rivers, and at times as far away as the sea. It is highly possible that they were first revealed in areas such as these, far away from their unusual location.

The tiny structure of a diamond gives it the property of being the unbreakable essence known to man, whether they are ordinary or artificial. The next hardest substance from which rubies and sapphires are formed, the diamond is known to be thousands of times harder than corundum. Even after many years of continuous showing off, diamonds will maintain their sharp ends and angles when most other stones will have become damaged and flaked

Many people anticipate a diamond to be unbreakable. This is inaccurate. A diamond's crystal structure has "firm" and "malleable" directions. A blow of adequate force, in a very precise way, can break, cut, crack or even smash a diamond.
