Diamond Colors

Contrary to popular belief, diamonds come in many colors, but when it comes to fine jewelry, diamond color is desribed in terms of "whiteness". Usually, precious pieces such as engagement rings are adorned with white diamonds, yet their perceived color can be affected by the diamond's shape and setting metal.


For most diamonds, color is described in terms of “whiteness”. Unlike fancy-colored diamonds, which are valued for their color intensity, white diamonds are valued for their lack of color.

The diamond color scale used by the diamond industry was developed by the GIA and places diamonds on a scale ranging from D to Z. Most retailers do not carry diamonds below L grade, which begin to show faint color.

Differences between diamond color grades can be very subtle. Diamonds that are J grade and above generally appear “colorless” to the untrained eye. However, color becomes easier to detect as diamond size increases. The larger the diamond, the more important color grades become.

Diamond shape and setting metal should also be taken into consideration, as they can affect perceived color.

Setting Metal

Once a diamond is set in jewelry, it becomes more difficult to see its true color. For lower color grade diamonds, yellow and rose gold can help make traces of color less apparent. White metals on the other hand, make hints of color more visible, and are therefore perfect for showcasing a colorless diamond.

Diamond Shape

Color tends to be less noticeable in brilliant cuts, due to the high number of facets. Step cuts, such as emerald, radiant, and asscher, are more revealing of color.

The most valuable of all color grades, the difference between D, E, and F diamonds can only be distinguished by experts.

D to F diamonds should be set in white metals. A warm or dark metal setting would affect the diamond’s perceived color, undermining its value.

A pure diamond will be completely transparent and colourless.

Any coloured diamond will contain interstitial impurities or structural defects. Generally, coloured diamonds are less valuable than pure versions.

A 2-carat diamond ring is a substantial size and will cost anything from $5,000 to over $60,000. The substantial difference in price can be attributed to the clarity of the diamond, its cut and the cut’s quality, as well as the colour of stone.
