A Diamond's Colour

Although most believe that diamonds are colorless, truly colorless diamonds are quite rare. The amount of color present actually affects the beauty and value of diamonds.

Diamonds range in a wide variety of colors from at "D" to "Z". Each letter represents a narrow range of color based on a diamond's tone and saturation. Once we pass "Z", we enter in to what is referred to as the "Fancy" colors.

ADX Tip: The closer the diamond is to "D" color grade, the more valuable it is.

Fancy-colored diamonds come in all colors of the rainbow, however, keep in mind that diamonds can be treated in many different ways to get a fancy color.

If you are looking for a natural fancy-colored diamond, make sure that it's certified. If you're interested in the fancy colors, we encourage you to speak to one of our jewelry experts

ADX Tip: Each person views color differently. You should view a selection of different diamonds side-by-side to determine what color appeals most to you.


Florescence has an effect on the visual appearance of the color of a diamond. Florescence refers to a diamond's tendency to emit a soft-colored glow when subjected to ultraviolet light.

The florescent glow is usually blue (which is the complementary color to yellow) and can therefore make diamonds of I-M color appear up to one grade whiter. Roughly 30 per cent of diamonds have some degree of fluorescence and may be a lower price because of the perceived defect.

Strong florescence can sometimes cause diamonds to appear milky, cloudy and/or oily in natural light which lowers their value.

ADX Tip: Be aware of lighting conditions when viewing diamonds as it can skew colors.

ADX Tip: If your ring has multiple diamonds, match the accent diamonds to the color grade of the centre diamond or choose a lower color grade.
