SEARCH NATURAL FANCY Gray COLOURED DIAMONDS
Coloured diamonds – also referred to as “fancy diamonds” – are a rare and mesmerising type of natural diamond found in a spectrum of remarkable shades. In the world of diamonds, rarity often determines value, and fancy coloured diamonds are far less common than traditional white diamonds.
Only around one in every 10,000 diamonds naturally develops with a fancy colour, making them some of the most prized and sought-after gemstones available. These diamonds occur in a wide variety of colours – from popular pinks and yellows to the exceptionally rare blues, greens, oranges, and purples.
Unlike colourless diamonds, which are valued for their lack of colour (graded on the GIA’s D-to-Z scale), fancy coloured diamonds become more valuable as the depth and vibrancy of their hue increases. These diamonds sit beyond the Z scale, with the most vivid examples being especially rare and valuable.
There are 12 primary colour categories, over 90 secondary hues, nine intensity levels, and more than 230 potential colour combinations. Many fancy coloured diamonds have blended tones due to secondary hues such as Gray, brown, or orange. The most desirable diamonds are those with rich, vivid colouring, strong saturation, and minimal dilution.
Among these, natural fancy Gray diamonds stand out for their soft, smoky appearance and sophisticated neutrality. Though often more understated than vivid coloured diamonds, high-quality Gray diamonds are deeply elegant and offer a refined alternative to traditional white stones.
One of the most well-known examples is the “Sloan Gray Diamond” – a 12.38-carat fancy Gray oval-cut gem renowned for its silvery brilliance and subtle allure.
Gray DIAMONDS
Fancy Gray diamonds are distinct among coloured stones. Their elegant colour is caused not by trace elements like boron or nitrogen, but typically by a high presence of hydrogen or dark inclusions that scatter light and impart a steel-like hue.
Unlike other diamonds that shine with rainbow brilliance, Gray diamonds possess a soft metallic sheen with a misty, romantic lustre. Their cool neutrality makes them a popular choice for modern engagement rings and minimalist luxury jewellery.
Although Gray diamonds are more accessible than the rarest colours, high-quality, naturally coloured stones with excellent clarity and cut remain highly sought after. They’re favoured in contemporary styles and often paired with white or black diamonds for contrast.
GRADING OF NATURAL FANCY COLOURED DIAMONDS
Grading coloured diamonds requires a specialist approach due to the complexity of hues and intensities. The Gemological Institute of America (GIA) is the foremost authority on diamond grading and uses a combination of printed references and master stones to assess colour.
Unlike white diamonds, which are graded for their lack of colour, fancy coloured diamonds are graded for hue and intensity. In the case of Gray diamonds, the GIA intensity scale (Faint to Fancy Dark) may apply, but the evenness of colour and origin are the most important factors.
