Diamond Brokers Queensland have access to some of the most spectacular fancy coloured diamonds available. When most people think of diamonds they will always assume that diamonds are white and although diamonds have always been found in a whole variety of colours they were only considered to be valuable if they were graded as white or near to colourless. Up until only a decade ago even the most pure and beautiful of fancy coloured diamonds were not considered valuable and had very little market demand. Now however there has been a steady increase in the demand for fancy coloured diamonds and their value has far exceeded that of a standard diamond. For clients wishing to invest into fancy coloured diamonds we suggest contacting our office for a full indepth consultation or selecting a fancy coloured diamond.
Fancy coloured diamonds for sale
It was not long ago that any fancy coloured diamond not matter how beautiful is colour was not considered valuable for sale if it was not white. Many of the pink, blue, red and yellow diamonds we see now selling at auction at record prices only a few decades ago were though unsellable for a worthwhile price. To categorise the price of a fancy coloured diamond is much more difficult than white diamonds and careful consideration and knowledge is required when purchasing a fancy coloured diamond for sale.
What makes a fancy coloured Diamond
There are many diamonds in the coloured diamond spectrum but not all diamonds that contain some form of colour will be considered fancy. Actually around 80% of all diamonds will contain some form of colouration however only a very small percentage of these will be considered to be of value as a fancy coloured diamond. Colour in a diamond is a natural occurance and can appear in any colour shade but what makes a fancy coloured diamond is the appeal of the colour to give a bright and pretty appearance. Colour is based on the purity or hue and the saturation level of the colour.
For coloured diamonds the hue is the main or dominant attributing colour of the diamond – pink, green, yellow, blue, ect.. A diamond of a pure hue is generally considered to be the rarest and most expensive of the coloured diamonds.
Secondary colours infuse with the primary colour and are expressed with an “ish” at the end, such as “greenish yellow”.
A grade like “purple pink” indicates the two colors are evenly shared in the diamond
GIA has a grading standard for each of the colour elements
Colour hue is sorted into three common ranges – high to low value:
- Greyish Blue
- Greeny Blue
Tone refers to the relative lightness to darkness of a hue:
- Very Light
- Medium Light
- Medium Dark
- Very Dark
Saturation is the intensity or strength of the colour. With most colours the favourable colour grade is Fancy Intense.
- Very Light
- Fancy Light
- Fancy Dark
- Fancy Intense
- Fancy Deep
- Fancy Vivid
GIA determines a color grade by locating a “color space” defined by its hue, tone and saturation. Once a hue is determined, the diamond is compared to a set of reference stones to locate the grade related to tone and saturation. The terms used for color grading are very specific and are not interchangeable. The value of a coloured diamond is predominantly measured by the colour grade over the quality of its clarity and cut grade diamonds the hue .
