The Wonder of Yellow Diamonds
If any stone can capture joy, the yellow diamond is unbeaten. Until the second half of the 19th century few yellow diamonds had been found, but today they are one of the most sought-after jewels, partly in thanks to Laurence Graff, who was one of the first to shine the spotlight on them.
Ever the innovator, ground-breaking techniques were developed by Graff to find new cuts that would best enhance the colour of yellow diamonds, rendering them the finest of their kind. Science explains their remarkable colour – it is nitrogen that billions of years ago differentiated a colourless diamond from its canary diamond sibling. Yellow is the only diamond colour whose grading begins on the lower end of the GIA D-Z diamond colour scale and continues into the ‘Fancy’ hues, giving yellows the widest and most fascinating range of variants.
The most prized are the four Fancy diamond grades, from Fancy Light to the top-of-the-range Fancy Vivid diamond, with its perfect equilibrium of colour and saturation. Enhancing a diamond’s colour is a skill that only a master cutter with at least ten years’ experience can attempt, and it is an audacious art. These inconceivably rare diamonds were formed deep within the earth some three billion years ago, and they are still being formed beneath our feet, waiting to be unearthed millions of years from now.
