The Sparkling World of Fancy Colour Diamonds

As Paris Couture Week takes center stage, the fashion world is electrified with excitement surrounding the incredible rarity and beauty of fancy colour diamonds. On July 2, 2025, the Natural Diamond Council (NDC) launched its inaugural Fancy Colour Diamond Report during this prestigious event, presenting an in-depth exploration of these mesmerizing gems. This innovative report celebrates the dazzling stories behind the world’s most coveted fancy colour diamonds and their significance in high fashion.

Unveiling New Discoveries

A highlight of this report is the discovery of an unprecedented purple diamond at Canada’s Diavik mine. This exceptional find has been described as one of the most important diamond discoveries in recent history, igniting massive interest across the diamond industry. Alongside this revelation, June 2025 saw record-setting auctions feature stunning fancy colour diamonds, including Christie's New York sale of the iconic Marie-Thérèse Pink diamond, which fetched nearly $14 million, and a remarkable fancy pink diamond ring at Sotheby’s that achieved $1.5 to $2 million.

Insights from The Fancy Colour Diamond Report

Collaborating with the Choron Group and the Fancy Color Research Foundation, NDC’s report provides a comprehensive guide to fancy colour diamonds, revealing their history, value, and unique characteristics. The document is enriched with contributions from industry experts, collectors, and retail professionals, showcasing the allure of these gems as symbols of prestige and artistry.

Fancy colour diamonds are renowned for their rich palette—ranging from vibrant reds and pinks to breathtaking blues and greens—where only a limited number of these exquisite gems are ever unearthed. For example, the rarity of red diamonds is particularly astounding, with very few surpassing two carats. The report highlights how the market for these colourful treasures has flourished, noting that fancy colour diamond prices have surged at an annual rate of 5.7% over the past two decades.

The Market Dynamics

Interestingly, while global trade challenges have led to uncertainty in the luxury sector, the fancy colour diamond market continues to thrive with resilience. According to Roy Safit, CEO of the Fancy Color Research Foundation, strategic repositioning in the market exemplifies its maturity and contributes to the enduring appeal of vivid colour diamonds.

The Craftsmanship Behind the Beauty

When it comes to transforming rough diamonds into lustrous gems, skilled cut artisans prioritize enhancing the color. Anshul Gandhi, CEO of Choron Group, emphasizes that fancy colour diamonds represent a unique and ultra-rare segment of the diamond market that requires exceptional craftsmanship. With decades of experience, Choron collaborates closely with luxury brands, ensuring that every diamond is a masterpiece reflective of nature’s grandeur.

To date, fancy colour diamonds have been sourced from various mines worldwide, including notable hotspots in Canada, Botswana, and South Africa. However, they account for only a tiny fraction of total diamond output, reaffirming their uniqueness and prestige.

Auction Highlights and Future Trends

The allure of fancy colour diamonds is magnified on global auction platforms. Recent auctions have showcased stunning pieces like the Mediterranean Blue diamond—a 10.03-carat Fancy Vivid blue diamond that sold for $21.4 million. In addition, the vibrant spectrum of colours that can be achieved by natural diamonds has monopolized attention during major sales, reflecting both their aesthetic appeal and investment potential.

As Paris Couture Week unfolds, the world can anticipate an explosion of rich colors on the runways, symbolizing the monumental role of fancy colour diamonds in high fashion. The report by NDC not only encapsulates the brilliance of these gems but also positions them as timeless representations of Earth’s rich heritage and artistic expression.
