A Magnificent Treasure Destined to Make History
A Magnificent Treasure: The Extraordinary Mediterranean Blue Diamond Set to Make History
An intense blue diamond of 10.3 carats, graded Fancy Vivid Blue, is poised to captivate the world at Sotheby’s Geneva high jewelry auction on May 13. Known as the Mediterranean Blue, this gem is, in every sense, singular.
Intense blue diamonds are celebrated not only for their beauty but for their extreme rarity. The Mediterranean Blue — bearing the highest color and clarity grade (VS2) conferred by the Gemological Institute of America (GIA) — represents a vanishingly small fraction of all diamonds in existence. As a member of the exclusive Type IIb classification, its singularity places it among the most coveted stones in the world. Its hue, which evokes the deepest reaches of the ocean, is nothing less than a testament to nature’s most extravagant gifts.
“There is no question that this extraordinary diamond shines on its own terms. Its captivating cushion cut draws out every depth of that ocean-blue color, placing it among the most remarkable gems to appear on the contemporary market,” said Quig Bruning, Head of Jewelry at Sotheby’s Americas and EMEA. Of the Mediterranean Blue, Bruning added that “any Fancy Vivid Blue diamond is a discovery worth celebrating — but one as compelling as this, surpassing ten carats, is news that deserves the world’s attention.”
A Gem Without Equal — and a Sale the World Will Be Watching
The story of this remarkable stone began in South Africa, where it was recovered as a 31.94-carat rough diamond in 2023. After more than a year of careful planning and six months of meticulous cutting, it was transformed to maximize its brilliance, yielding a modified cushion cut that incorporates triangular and kite-shaped facet elements. The result is a testament not only to nature’s generosity but to the mastery of the finest craftsmen in the jewelry world.
Estimated at approximately $20 million, the Mediterranean Blue will embark on a global tour prior to the sale, opening with an exclusive presentation in Abu Dhabi on April 8 before traveling to Taipei, Hong Kong, and New York. The itinerary is designed not merely to impress collectors and connoisseurs, but to awaken the broader world to one of the most intriguing gemstones of our time.
The auction of the Mediterranean Blue will be, without question, a defining chapter in the history of high jewelry. With its rare combination of singularity, beauty, and an extraordinary provenance, this gem is destined to be more than a collector’s prize — it is a reminder that, from time to time, nature produces something that deepens our sense of wonder. For those who prize the truly exceptional, this diamond is an event not to be missed.
