From Mughal Vaults to Geneva: The Golconda Blue Diamond’s $50 Million Journey

The Golconda Blue: A Royal Legacy in Vivid Brilliance

Geneva, Switzerland – Christie’s Magnificent Jewels sale will present an extraordinary treasure on 14 May 2025: the 23.24-carat Golconda Blue, a Fancy Vivid blue diamond of unparalleled rarity and historical significance. Once gracing the collections of Indian royalty, this exceptional gem is poised to captivate the world’s most discerning collectors, with estimates reaching $35–50 million (₹300–430 crore).

A Diamond of Mythic Rarity

Classified as a Type IIb diamond—a category representing just 0.1% of all natural diamonds—the Golconda Blue derives its mesmerizing hue from trace boron impurities, a phenomenon as rare as it is breathtaking. With VS1 clarity, its crystalline structure exhibits flawless transparency, allowing light to dance through its depths with unmatched brilliance.

A Journey Through Time

This legendary stone has passed through the hands of history’s most illustrious owners and artisans:

Indian Maharajas, who treasured Golconda diamonds as symbols of divine favor.

Master jewelers—from Chaumet’s royal commissions to Harry Winston’s mid-century showcases—who transformed it into wearable art.

Contemporary virtuoso JAR, who has mounted it in a sleek, modern ring, juxtaposing its ancient origins with timeless elegance.

The Golconda Legacy

Mined from the historic mines of Golconda—now exhausted—this diamond shares its lineage with the Hope Diamond and the Koh-i-Noor, gems that have shaped empires and ignited passions for centuries. Its very existence speaks to the peerless craftsmanship of Mughal-era lapidaries, who prized Golconda stones for their otherworldly purity.

A Sale for the Ages

As the largest Fancy Vivid blue diamond from Golconda ever offered at auction, the Golconda Blue is more than a gemstone—it is a cultural touchstone. Christie’s anticipates fierce bidding from royal families, luxury maisons, and private collectors, each vying to own a piece of history.

A Legacy Woven into Royal History

Emerging from the legendary Golconda mines of present-day Telangana—now exhausted, yet forever immortalized by the stones they yielded—the Golconda Blue carries a pedigree shared with the most storied gems in history:

  • The Hope Diamond (45.52 carats), shrouded in mystery and tragedy
  • The Koh-i-Noor (105.6 carats), centerpiece of the British Crown Jewels
  • The Darya-i-Noor (182 carats), a shimmering treasure of the Iranian Crown
  • The Regent Diamond, which gleamed from the hilt of Napoleon’s sword
  • The Idol’s Eye (70 carats), ransom for a princess’s freedom
  • The Agra Diamond, worn by Emperor Babur as a symbol of mercy
  • The Wittelsbach Blue, a royal Spanish dowry in 1664
  • These gems, like the Golconda Blue, were born from the same earth, cut by the same master hands, and coveted by the same emperors, conquerors, and kings.
