Read a fancy-colour diamond through its hue, tone, saturation and distribution. Keep the laboratory’s complete colour description beside the photographs, because every modifier contributes to the description.
Keep the full wording
The 3.05 ct Fancy Deep Greenish Yellow diamond is a useful example. Its recorded description includes both the colour combination and the Fancy Deep designation. Broad step facets frame that colour in an octagonal outline.
Watch how the cut distributes colour
View the diamond face-up and at a slight tilt in neutral light. Look for concentrated colour, softer areas and dark reflections. Repeat with the intended metal nearby, since the surroundings can change the appearance on the hand.
For an antique jewel, inspect the mounting as well: a closed back, foil or darkened metal may influence the colour you see. Request the recognised laboratory report, confirm its colour-origin finding and read any treatment comments. For sourcing, share the colour description and the visual effect you prefer through the Trade Sourcing Desk.
