The Evolution of Diamonds: From Ancient Relics to Modern Luxury
As Editor of StyleLujo.com, I’ve seen the world of luxury evolve in ways both subtle and spectacular. But few objects hold the same timeless allure as diamonds—the undisputed kings of precious stones. These glittering gems have long been synonymous with power, prestige, and desire, shaping economies and defining status for centuries. And today, the sale of The Mediterranean Blue, a breathtaking 10.03-carat Fancy Vivid Blue diamond, reminds us that the diamond market is as electrifying as ever.
The history of diamonds dates back over 3,000 years, when they were first discovered in India and reserved exclusively for royalty and religious figures. Fast forward to the 15th century, and diamonds became a European obsession, worn by aristocrats and cemented as the ultimate status symbol. But it wasn’t until the late 19th century, with the discovery of vast diamond mines in South Africa, that diamonds became widely accessible. De Beers, the industry titan, famously coined the phrase “A Diamond Is Forever”, solidifying diamonds as essential tokens of love and commitment.
Despite their widespread appeal, blue diamonds remain extraordinarily rare. Less than 0.1% of all mined diamonds show any trace of blue coloring, making them among the most desirable and valuable gems on the market.

Shape and Cutting Style: Cushion Modified Brilliant
The Mediterranean Blue: A Modern Masterpiece
Enter The Mediterranean Blue—a newly mined diamond from the legendary Cullinan mines of South Africa, the very same source that yielded the 530-carat Great Star of Africa, the largest faceted colorless diamond in existence. Unlike traditional white diamonds, the deep saturation of this Fancy Vivid Blue gem places it in a rarefied league—one that collectors and connoisseurs around the globe were desperate to get their hands on.
The Mediterranean Blue is an extraordinary achievement in the world of fine jewelry—an exquisite 10.03-carat Fancy Vivid Blue diamond that represents the pinnacle of rarity, precision, and craftsmanship. From its origin in the famed Cullinan mines of South Africa to the meticulous six-month cutting process that yielded its flawless cushion modified brilliant shape, this gemstone embodies both history and innovation. Its saturation and brilliance are nothing short of mesmerizing, earning it the highest possible color grading from GIA and a coveted Type IIb classification, placing it among the rarest diamonds in existence. As someone deeply immersed in luxury and style, I can confidently say this is more than just an investment—it is a masterpiece that reflects both the artistry and science behind diamond craftsmanship.
Beyond its striking beauty, what truly sets The Mediterranean Blue apart is its undeniable presence. The intensity of its hue rivals some of the most celebrated blue diamonds in history, and its $21.5 million sale price at Sotheby’s Geneva speaks volumes about its value in today’s market. The enthusiasm surrounding this gem—from its unveiling in Abu Dhabi to its tour across the Middle East, Asia, and the United States—has confirmed its stature as a coveted collector’s piece. This diamond isn’t just a rare find; it’s a testament to the continued allure of blue diamonds and the unwavering demand for excellence in high jewelry. As a curator of luxury, I recognize that beyond the numbers, The Mediterranean Blue is an emblem of sophistication, prestige, and the enduring power of diamonds as objects of desire.
Moments ago, at Sotheby’s High Jewelry auction in Geneva, The Mediterranean Blue shattered expectations, igniting a three-minute bidding battle that saw its price skyrocket to $21.5 million. In a spectacular moment, it was acquired by a private American collector, adding yet another chapter to the ongoing legacy of blue diamonds.
What makes The Mediterranean Blue even more extraordinary is its cushion modified brilliant cut, accentuating its brilliance and maximizing light reflection. Fashioning a blue diamond is no simple feat—it took over six months of meticulous study and craftsmanship to perfect its final shape, ensuring its face-up color was as mesmerizing as possible.
Today’s sale reaffirms an undeniable truth: the demand for exceptional diamonds is stronger than ever.


A Market Defined by Rarity
The Mediterranean Blue is only the latest in a long line of jaw-dropping sales in the high jewelry world.

More recently, in 2022, The De Beers Blue, a 15.10-carat step-cut Fancy Vivid Blue diamond, commanded $57.5 million at Sotheby’s Hong Kong.
Yet beyond their staggering price tags, diamonds remain deeply symbolic. Whether worn as a personal emblem of wealth or preserved as part of an elite collection, they hold an unmatched position in the luxury world.
With The Mediterranean Blue now in the hands of an esteemed collector, one thing is certain: its legacy is only just beginning.
