Report number 2215641667, dated April 30th 2021 Fancy coloured diamonds are far more rare than diamonds in the normal colour range.A diamond, particularly a yellow one that shows colour that’s deeper or more intense or vivid than a Z colour stone, moves it from the ranks of normal coloured diamonds and into the realm of fancy-coloured diamonds.This rarity has a profound impact on diamond value. Understanding and describing colour when it comes to precious gemstones can be challenging. The 3 elements used to describe colour are hue, tone and saturation.The hue of a stone is the basic impression of a colour. But in order to get a complete picture of colour, you have to also consider tone and saturation. Tone is the amount of lightness or darkness in a colour and saturation is the strength, purity or intensity of the hue. The GIA uses an official grading system to describe the combined effect of tone and saturation on the diamonds hue. The scale is divided into 9 categories as follows: FaintVery Light Light Fancy Light Fancy Fancy Intense Fancy Dark FancyVivid A diamond’s cut can have an influence on its apparent colour and the bigger the diamond, the more obvious the colour.
