AN IMPORTANT FANCY COLOURED DIAMOND RING The cushion-shaped diamond, weighing 7.00cts, within a six-claw setting, mounted in 14K gold, ring size D½ Accompanied by a report from GIA laboratory in America, stating that the diamond weighing 7.00cts, is of Fancy Yellow colour, SI1 clarity. Report number 15124514, dated October 5th 2017 Fancy-Coloured Diamonds Diamonds that come in colours beyond the normal colour range of D to Z are known as Fancy-Coloured Diamonds. They can come in colours such as deep yellows and browns as well as pinks, oranges, blues and greens. Tiffanys famous yellow diamond, The Tiffany a cushion shaped Canary Yellow diamond, has firmly planted the desire for this wonderful yellow hue to grace our fingers or neckline. Yellow diamond engagement rings sported by Hollywood stars, such as Olivia Palermo, Jennifer Lopez, Heidi Klum and Jessica Alba prove that our adoration of yellow diamonds is steadfast. However, this love affair with yellow diamonds is nothing new, there is a long history of extraordinary yellow diamonds that gained fame, both as exquisite examples of the beautiful nature of diamonds and because of the famous people who wore, bought and sold them. Some examples of notable yellow diamonds are The Allnatt (cushion-cut diamond, Fancy Vivid Yellow 102.29ct), The Florentine (irregular nine-sided shape, Light Yellow, 139ct), The Incomparable (shield- shaped step-cut, Fancy Brownish Yellow, 407.48ct) The Mouna (cushion-cut diamond, Intense Yellow, 112.53ct), The Porges (Asscher-cut, Yellow, 78.53ct) and The Red Cross (cushion-cut, Canary Yellow, 205.07ct). Fancy coloured diamonds are far more rare than diamonds in the normal colour range. A diamond, particularly a yellow one that shows colour thats deeper or more intense or vivid than a Z colour stone moves it from the ranks of normal coloured diamonds to the realm of fancy-coloured diamonds. Rarity has a profound impact on diamond value. Understanding and describing colour 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 a grading system to describe the combined effect of tone and saturation on the diamonds hue. The scale is divided into 9 categories as follows: Faint Very Light Light Fancy Light Fancy Fancy Intense Fancy Dark Fancy Vivid A diamonds cut can have an influence on its apparent colour and the bigger the diamond the more obvious the colour.
