| Grades in the
colour of diamonds range
from D-Z, D being truly colourless and of the highest quality. E and
F are also graded as colourless while G, H, I and J are near
colourless.
Stones grades K, L, and M will have obvious hints of colour and as
the scale approaches P you may find subtle changes in hue and tone.

The exceptions to the rule are "Fancy" diamonds- in well-highlighted
colours that include pink, blue, red, green, and canary yellow. These
are particularly rare and highly treasured. To appreciate the quality
of a colourless diamond, compare several stones side by side. |

Most of the diamonds between
colours D to J appear colourless the
only way to tell the difference is on a white paper and by the lab
certificate.
