SEARCH NATURAL FANCY BROWN 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 grey, brown, or orange. The most desirable diamonds are those with rich, vivid colouring, strong saturation, and minimal dilution.
Among these, natural fancy brown diamonds stand out for their warm, earthy tones and understated elegance. Though once considered unconventional, high-quality natural brown diamonds are now recognised for their unique charm and increasing popularity in fine jewellery.
One of the most iconic examples is the “Golden Jubilee Diamond” – a remarkable 545.67-carat fancy yellowish-brown diamond, famously gifted to the King of Thailand.
BROWN DIAMONDS
Fancy brown diamonds are unique among coloured diamonds. Their warm, chocolate-to-cognac hues are typically caused by distortions in the diamond’s crystal lattice – a natural formation process that alters the way light is absorbed and scattered within the stone.
These diamonds range in tone from subtle champagne to deep, intense brown, sometimes with secondary colours such as pink, orange, or yellow. Their earthy elegance, combined with their natural origin, makes them a stylish and versatile choice for contemporary and vintage-inspired jewellery designs.
Natural brown diamonds are more abundant than some other fancy colours, but stones with strong, uniform colour and excellent cut quality remain highly desirable. They have gained popularity in recent years for their distinctive appearance and modern appeal.
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 brown diamonds, the GIA typically uses intensity descriptors such as Light, Fancy Light, Fancy, Fancy Intense, and Fancy Deep, depending on the saturation and tone.

Frequently Asked Questions About Fancy Brown Coloured Diamonds
What is a fancy brown diamond?
A fancy brown diamond is a natural diamond with a noticeable brown hue, caused by structural distortions within the crystal lattice. These distortions affect how light travels through the diamond, giving it its warm and earthy colour.
Are brown diamonds natural?
Yes, brown diamonds occur naturally and are available in a variety of shades, from champagne to deep chocolate. At Rêve Diamonds, we only offer natural fancy brown diamonds that are GIA-certified to confirm their authenticity and untreated origin.
What makes brown diamonds different from other fancy coloured diamonds?
Brown diamonds are among the most affordable fancy colours and are valued for their warm, organic tones. Their colour results from lattice distortions rather than trace elements, giving them a unique character and visual appeal.
Are fancy brown diamonds valuable?
Yes, especially when they are large, well-cut, and display even, vivid colouring. While generally more accessible than rarer colours like blue or red, high-quality natural brown diamonds are becoming increasingly popular and valuable in the fine jewellery market.
Are brown diamonds a good choice for engagement rings?
Absolutely. Brown diamonds offer a warm and romantic alternative to traditional white diamonds. They pair beautifully with rose gold and vintage settings and are perfect for those seeking a non-traditional yet timeless design.
How can I tell if a brown diamond is natural or treated?
Always request a certificate from a trusted gemmological authority such as the GIA. This will confirm whether the brown diamond is natural in both origin and colour. Treated stones do exist, so certification is important for transparency and value.
Are brown diamonds a good investment?
Natural fancy brown diamonds can be a smart investment, particularly as their popularity grows and consumers seek distinctive alternatives to traditional stones. Their rich colour and timeless style give them strong appeal among collectors and jewellery lovers.
How should I care for a brown diamond?
Brown diamonds are as durable as other types of diamonds. Clean them gently with mild soap and a soft brush, avoid ultrasonic cleaners, and have your jewellery checked regularly by a professional to ensure the stone remains secure.
