Colour
The term colour in regard to diamonds is misleading as
it is a diamond's lack of colour that is most highly sought after. The
colour grading system ranges from D to Z. D being completely colourless and Z
having a tint of brown or yellow. The untrained eye will tend to only see colour
at grade M.
The colour grading system is as follows:
The colour grading system is as follows:
D,E, and F are considered completely colourless. This means that the stone will be colourless facing upward and also out of it's setting facing downward.
G,H,I, and J are in the Near Colourless range and are also completely colourless face up. It is only out of their setting, face down against a white background that a trained diamond grader will see a hint of colour.
The grades below this will begin to show colour face up in their settings from grade K upward, becoming more noticeable further up the scale.
