Diamond is the most precious of the gemstone. The word “Diamond” originally comes from the Greek word “Adams” which means “Unconquerable”.
Diamonds are formed by nature in the upper mantle of the earth’s crust. Crystallization took place millions and millions of years ago, under enormous pressure and at a very high temperature. Before being forced to the surface of the earth, they were stored in the upper mantle of the earth at a depth of 150-300km below the surface. The atoms in diamond are equidistant from one another.

Growth of environment, chemical impurities can cause structural distraction; they can even scatter the crystal. In diamonds color vary so widely, sometimes it becomes difficult to judge the exact color.
