NDC Unveils Fancy Colour Diamonds Report

The Natural Diamond Council (NDC) has officially released its comprehensive Fancy Colour Diamonds Report, offering an in-depth exploration of one of the most fascinating categories in the diamond industry.

This report covers everything from the geological origins and colour grading of fancy colour diamonds to their market performance, iconic stones, and auction highlights.

Formation & Origins of Fancy Colour Diamonds

According to the NDC Fancy Colour Diamonds Report, these rare diamonds were formed billions of years ago under extreme geological conditions deep within the Earth.

Each colour is the result of unique natural processes:

• Pink & Red Diamonds: Caused by crystal lattice distortions from immense pressure.
• Yellow & Orange Diamonds: Result from nitrogen traces.
• Blue Diamonds: Coloured by boron deep within the Earth’s mantle.
• Green Diamonds: Affected by natural radiation over millions of years.
• Black Diamonds: Gain colour from graphite and mineral inclusions.

Every fancy colour diamond is a stunning example of nature’s artistry.

Grading Beyond the 4Cs: How Fancy Colour Diamonds Are Evaluated

Unlike traditional colourless diamonds, fancy colour diamonds are graded primarily on their colour intensity.

• Hue: Dominant colour.
• Tone: Lightness or darkness.
• Saturation: Intensity of the colour.

Diamonds graded as “Fancy Vivid” or “Fancy Deep” are among the most valuable. The report highlights that colour plays the biggest role in determining price and rarity.

Cutting Techniques That Enhance Colour Brilliance

The report emphasises the importance of cutting styles specifically designed to maximise colour brilliance. Cuts like the radiant cut are popular because they amplify colour through precise light dispersion, even if it means sacrificing some carat weight.
