Information about the colour of the diamond
The great majority of diamonds are classified in the category known as “cape”, which varies from the perfectly colourless (white) to a slight yellow tint.
D Exceptional White + formerly known as "Jager"
E Exceptional White form. "River"
F Extra White +
G Extra White form. "Top Wesselton"
For these colours demand a recognised certificate (GIA, HRD or IGI) testifying the quality of these rare whites.
H White form. "Wesselton"
I Slightly tinted white form. "Top Crystal"
These are very beautiful whites (called “near colourless”), above the “commercial” quality. A certificate is always recommended.
J Slightly tinted white form. "Crystal"
K/L Tinted form. "Top Cape"
These colour diamonds still seem white to the naked eye for non professionals if they are of a small size (below 0,10 ct) but beyond this, a colour saturation is noticeable.
M And below:
tinted, very pale yellow "light cape, cape, dark cape"
Fluorescence : fluorescence is a luminous effect that happens with only few diamonds when they are exposed to ultraviolet rays.
