Learn About Diamond Grading
Most diamonds of gem quality used in jewelry vary in shade from completely colorless down to a visible tint.
The rarest and most expensive are diamonds in the colorless range graded D,E and F on a scale that descends to Z.
Diamonds with more color than Z, or in other shades such as orange, pink, blue, etc. are classified as "Fancy Colored Diamonds".
Since diamonds form under extreme heat and pressure, internal and external characteristics are common. These characteristics help gemologists identify individual stones.
In order to grade the clarity of a diamond, it is necessary to observe the number and nature of external and internal characteristics of the stone, as well as their size and position.
While probability determined the color and clarity of a diamond, man is responsible for the cut quality which brings it to life.
The planning, proportions, cutting precision and details of finish determine how brilliant, dispersive and scintillating the diamond will be. If the cutting factors under man's control are not optimized, the appearance of the diamond can be adversely affected.
