How a Diamond is Formed. In order for diamond to form there must be an available source of carbon and relatively narrow ranges of temperates and pressures must align. This happens around 100 miles below the crust. Once crystalized the diamonds must be rapidly transported to the surface without undergoing substantial change.
For this, you will need a tape, which measures in millimeters. Now, choose a clean and flat surface to place your selected loose diamond. Set the diamond face in upward direction. Remember, you have to measure the diameter of the diamond at the widest point. Hence, for different shapes, it will be different.
