Understanding Diamond Colour: What Do D-Z Grades Mean?
When choosing a diamond, colour is one of the 4 Cs that determines its beauty and value. While many people assume diamonds are completely colourless, most actually contain subtle hints of yellow or brown.
White Diamond Colour Grades:
The industry standard GIA colour scale ranges D to Z:
D-F (Colourless): The rarest and most valuable, with an icy-white appearance.
G-J (Near Colourless): Exceptional value, appearing white to the naked eye in most settings.
K-M (Faint): A soft, warm tint becomes visible.
N-R (Very Light): Noticeable yellow or brown colouring.
S-Z (Light): Clearly visible colour.
Fancy Coloured Diamonds
Unlike white diamonds, fancy coloured diamonds are prized because of their colour. These stunning natural hues are created by trace elements or unique conditions during the diamond's formation.
Popular fancy colours include:
- Yellow - The most common fancy colour, created by traces of nitrogen
- Champagne & Chocolate - Beautiful natural brown hue diamonds, ranging from light champagne tones to rich chocolate hues.
- Blue - Exceptionally rare, with their colour resulting from traces of boron.
- Pink & Red - Among the rarest diamonds in the world, believed to form from unique changes within the crystal structure.
- Green - Created by natural radiation exposure over millions of years.
- Orange, Purple & Violet - Highly sought-after colours formed through unique combinations of trace elements and crystal structure.
- Black - Their dramatic appearance comes from dense natural inclusions within the diamond
