People often tend to choose colourless diamonds ever since, we often called them white diamond. In fact, the value of a diamond is highly reflected on the colour diamond due to dwindling supply. Colour diamonds has unique characteristics due to different formation, red diamond is formed because of crystal structure distortion during the formation process, blue diamond is formed due to the absorption of trace boron elements, green diamond is formed due to change of crystal structure caused by natural radiation.

“Hue” refers to the basic colour such as red, green, blue and all those colours in between. GIA define a total of 27 hues for diamond colour. “Saturation” refers to the strength of the colour, GIA set a total of 6 saturation grades. “Tone” refers to the brightness of colour, GIA set a total of 7 tone grades.
GIA defines 9 intensity grades based on the combination of colour hue, tone and saturation. The weakest is “Faint” and the strongest is “Fancy Deep”. However, in the diamond trading market, “Fancy Vivid” has the most valuable colour grade.
Strong fluorescence reduces the value of a white diamond. In contrast, the presence of fluorescence on colour diamond may increase the saturation of its original colour, in consequence, enhance the diamond colour, leading the opportunity to let diamonds become a rarer treasure.
Rarity
Natural colour diamonds are extremely rare gemstone, different colours represent different degrees of rarity hence different in the price level. Red and Blue diamonds are most rare and extremely expensive, pink, green and orange diamonds are very cherished, the popularity followed by yellow and brown diamonds that remains at high value.
Every 250 tonnes of ore must be mined to extract 1 carat of white diamond, where only 20% can become jewelry-grade diamond. The discovery ratio of colour diamond is even lower than the white diamond, to excavate every 10,000 pieces of white diamonds in order to find 1 natural coloured diamond, colour diamonds are extremely rare.

Colour Origin and Distribution
Fancy colour diamond is all about colour, but the cause of the colour can either be found natural or manual processed, the prior and the latter has huge difference in value. So, before buying colour diamond, be sure that the colour has been inspected for any post-treatment, as well as pay attention to whether the colour is uniformly distributed.
Treated diamonds are rich in colour, but its value is far lower than natural diamonds. The most common artificial colour processing methods are high-pressure-high-temperature (HPHT) and Artificial Irradiation. The prior method will place diamonds into a high pressure and high temperature environment to enhance its colour; the latter is to alter diamond’s crystal structure to strengthen or evenly distribute its colour.
Colour distribution also affects the optical sense and values of colour diamond. Colour distribution refers to the uniformity of the colour. Its rating is either “Even” or “Uneven”, it is an essential requirement for a high quality natural colour diamond.
Carat Weight, Clarity & Cut
The focus of colour diamonds is truly all about the colour. Before processing, the cutter will study how to outperform the colour when constructing cut. This requires a lot of experience and vision, cutting colour diamonds require balancing the weight, clarity, and cut to maximize the degree of colour and brilliance of a diamond.
Carat Weight is the second most important factor in determining the price of fancy colour diamonds. As fancy colour diamonds are rarer than colourless diamonds, the larger the carat weight, the higher the price. For instance, the size of 0.10-0.50ct. pink diamond or 0.70-1.50cts. yellow diamond are considered as entry level, 1.0ct. or above are considered as collection level providing a good form of investment.
Although clarity is one of the key factors when evaluating white diamond, it is not necessarily the case for fancy colour diamond. The origin colour often hid the visibility of inclusions, therefore the impact of clarity is reduced. In some cases, even if the diamond has unpleasant clarity but rich in colour, the diamond will still be sought after by collectors.
Fancy colour diamond often comes in cushion shape. This is because the objective of cutting colour diamond is based on the ability to highlight the colour. The cushion is an ideal shape for natural fancy colour diamonds since it has a large volume to allow more light to travel within the diamond in order to show the diamond’s natural colours best. Whereas it has a different objective when cutting a white diamond to highlight the sparkle and brilliance.
