Diamond Colour

The diamond evaluation begins with the absence of colour. While most other gems are reviled for their brilliant colours, it is the absence of colour that increases the value of a diamond. A chemically pure and structurally perfect diamond has no hue and appears crystal clear. The colour scale begins with the letter D, representing colourless, and continues to the letter Z as the presence of colour increases. A truly colourless diamond, a D on the grading system, is extremely rare.

These colour distinctions, while invisible to the untrained eye, contribute significantly to the overall uniqueness of each diamond.

The D-Z diamond grading system, established by the GIA, is how each diamond receives its colour grade; the most popular grade is a near colourless rating since most diamonds do contain subtle hints of yellow or brown. These slight colour distinctions impact the overall quality and price of each diamond.
