One of the world's rarest pink diamonds is about to make its auction debut. The spectacular Bulgari Pink, weighing exactly 24 carats, has remained in the private collection of a distinguished European aristocratic family for more than seven decades. Now, this extraordinary gemstone, celebrated for its exceptional purity and intense pink color, will be offered at Christie's in Geneva with an estimated value of $18 million, although the final selling price could be considerably higher.
Some gemstones are valued not only for their carat weight but also for their history, provenance, and extraordinary rarity.
The Bulgari Pink is precisely such a treasure. The magnificent pink diamond will be one of the highlights of Christie's prestigious Magnificent Jewels auction in Geneva on November 10, 2026.
Set in a ring created by the renowned Italian jewelry house Bulgari, the impressive gemstone has remained completely out of the public eye for decades.
Its appearance on the market represents an exceptionally rare opportunity for collectors of high jewelry, particularly at a time when natural pink diamonds are becoming increasingly difficult to acquire.
Combining remarkable gemological characteristics with an extraordinary family history, the Bulgari Pink is expected to attract considerable attention from some of the world's most discerning collectors.
From an Indian Mine to Bulgari's Legendary Jewelry Workshops
The story of this remarkable diamond begins in the 1950s, when the current owner's great-grandfather acquired a rough gemstone originating from India.
The stone was subsequently entrusted to Bulgari, whose artisans transformed its natural beauty into an exceptionally elegant ring, giving the diamond its distinctive rectangular shape with step-cut facets.
During this period, the Roman jewelry house was strengthening its position among the most prestigious names in the world of luxury jewelry.
Its creations attracted European aristocrats, Hollywood stars, and influential collectors, including Elizabeth Taylor, Richard Burton, and Audrey Hepburn.
The Bulgari Pink soon became part of a private family collection, where it remained for more than 70 years without ever appearing at a public auction.
This remarkable ownership history adds another dimension to its desirability.
For serious collectors, provenance and a documented history can be almost as important as the gemological characteristics of a precious stone.
The fact that the diamond has remained within the same family for generations gives it a particularly compelling identity, connecting its extraordinary physical beauty with a story of heritage and discretion.
An Exceptional Diamond with Intense Pink Color and Extraordinary Purity
The Bulgari Pink weighs exactly 24.00 carats, but its most important characteristic is the rare combination of size, color, and purity.
The diamond carries the prestigious Fancy Intense Pink designation, indicating a pronounced and naturally intense pink hue.
Its rectangular step cut further emphasizes the depth of color and elegance of the stone, while its Type IIa classification places it among the most chemically pure natural diamonds.
Diamonds belonging to this category account for less than two percent of natural diamond production.
They are characterized by exceptionally low nitrogen content, making them particularly prized among gemstone connoisseurs.
The combination of an impressive 24-carat weight, rare pink coloration, and Type IIa classification makes the Bulgari Pink an extraordinary gemstone of a kind that seldom appears on the international market.
Unlike more conventional white diamonds, exceptional natural pink diamonds are prized for the remarkable geological circumstances responsible for their distinctive color.
Their scarcity, especially in larger sizes, has helped establish them as some of the most desirable gemstones in the world of high jewelry.
The Closure of the Argyle Mine Has Made Pink Diamonds Even More Desirable
Interest in natural pink diamonds has increased significantly in recent years, particularly following the closure of the famous Argyle mine in Western Australia in 2020.
For decades, this mine was one of the world's most important sources of pink diamonds, and its closure substantially reduced the availability of these exceptionally rare gemstones.
As supplies become increasingly limited, large, high-quality pink diamonds have grown more desirable among collectors and investors in exceptional jewelry.
This scarcity is particularly significant for stones that combine substantial carat weight with outstanding color characteristics.
The Bulgari Pink possesses precisely the qualities that distinguish the most prestigious examples within this already exclusive category.
Its estimated value of $18 million could therefore represent only the starting point for competitive bidding, although the final auction result remains uncertain.
The gemstone's combination of rarity, historical provenance, and association with one of Italy's most celebrated jewelry houses gives it a distinctive position within the market.
Record-Breaking Sales That Suggest Strong Collector Interest
The history of prestigious jewelry auctions demonstrates that exceptional pink diamonds can achieve extraordinary prices.
One of the most notable examples is the Sakura Diamond, a 15.81-carat gemstone with a purple-pink hue that Christie's sold in 2021 for nearly $30 million.
An even more impressive result was achieved by the CTF Pink Star, an oval-shaped pink diamond weighing almost 60 carats and carrying the prestigious Fancy Vivid Pink and Internally Flawless classifications.
The remarkable gemstone sold at Sotheby's in Hong Kong in April 2017 for an astonishing $71.2 million.
The sale established a record for the most expensive diamond or gemstone ever sold at auction.
Although the Bulgari Pink differs from these celebrated stones in color, cut, and other characteristics, its impressive size and exceptional provenance certainly place it among the most intriguing gemstones to appear on the market this year.
Auction results for rare colored diamonds depend on numerous factors, including color intensity, clarity, cut, provenance, and the level of interest among prospective buyers.
Nevertheless, the historic performance of exceptional pink diamonds provides a compelling context for the upcoming sale.
Geneva Prepares for One of the Year's Most Exceptional Jewelry Auctions
Christie's Magnificent Jewels auction is scheduled for November 10, 2026, at the luxurious Four Seasons Hotel des Bergues in Geneva.
Interested collectors and high jewelry enthusiasts will have an opportunity to view the Bulgari Pink during a public exhibition running from November 5 to 10.
Its first public appearance after more than seven decades represents a significant moment for the international gemstone market.
It also offers a rare opportunity to appreciate an extraordinary example of Italian high jewelry craftsmanship, created during an important period in Bulgari's history.
Beyond its remarkable estimated value, the diamond embodies a fascinating combination of natural rarity, aristocratic provenance, and the artistic heritage of one of the world's most celebrated jewelry houses.
For collectors, the opportunity to acquire a gemstone with such an unusual history is particularly compelling, especially when its exceptional characteristics are combined with decades of private ownership.
The Bulgari Pink is not merely an $18 million diamond. It is an extraordinary testament to timeless beauty, jewelry-making tradition, and a level of rarity that continues to become more precious.
Whether it exceeds expectations at the upcoming auction remains to be seen, but its remarkable history has already secured its place among the most fascinating jewelry discoveries of 2026.
