This exceptional necklace represents a remarkable fusion of history, artistry, and gemology. Let's delve into the captivating details of this masterpiece, including its significant owners, the story behind its creation, size, carat, gemological details, and value.


Creation and Initial Ownership

Commissioned by Napoleon Bonaparte in 1811 for his wife, Empress Marie Louise, to commemorate the birth of their son, the necklace was crafted by the celebrated jeweler François Regnault Nitot. The construction took over a year, with a cost then estimated at 376,400 French francs – a staggering amount even by today's standards.



The necklace consists of 234 diamonds, totaling approximately 140 carats. It is composed of 28 large stones, ingeniously linked by smaller diamond clusters. The unique design features a looped chain with drop-shaped motifs, displaying an elegant balance of size and symmetry.


Gemological Detail

The diamonds in the necklace are predominantly Old Mine cuts and cushion cuts, emphasizing the period's craftsmanship. While detailed grading reports of the individual diamonds are not publicly available, the overall quality is considered to be exceptional, with stones of high color and clarity.

Napoleon Bonaparte, the formidable French Emperor, was known for his sweeping military campaigns, strategic brilliance, and grand gestures of love. Among the most symbolic of these gestures was his commissioning of the exquisite Napoleon Diamond Necklace for his second wife, Empress Marie-Louise, in celebration of the birth of their son, Napoleon François Joseph Charles Bonaparte.

The creation of the necklace was entrusted to François Regnault Nitot, a master jeweler of the era. Napoleon's vision was a piece that would not only demonstrate his immeasurable affection for Marie-Louise but also symbolize the might and elegance of the French Empire. He spared no expense, and the result was a breathtaking masterpiece composed of 234 diamonds, totaling around 140 carats.

The delivery of the necklace to Empress Marie-Louise was an event filled with splendor and emotion. Presented to her in 1811, the necklace's unrivaled beauty and the sentiment behind its creation moved the Empress. It was more than a piece of jewelry; it was a tangible embodiment of Napoleon's love and a statement of her status as the Empress of the French Empire.

Though the necklace was a powerful symbol of their union, it was rarely worn by Marie-Louise in public. Despite this, it remained a cherished possession, reflecting a moment in time when love, power, and artistry converged to create a timeless testament to one of history's most compelling relationships. The story of how Napoleon gave the necklace to Marie-Louise is not only a romantic tale but also a glimpse into the opulence and cultural values of early 19th-century French royalty.

After Napoleon's defeat and exile, she returned the necklace to the crown jewels of France.


The Bourbon Restoration

The necklace became a symbol of the restored Bourbon monarchy under Louis XVIII. In 1820, it was slightly modified to remove some emblems related to Napoleon.


Auction and Private Ownership

In 1887, the French Third Republic made the historic decision to auction off the crown jewels, a collection that included the famed Napoleon Diamond Necklace. The decision marked a clear departure from the monarchy's legacy and led to an intense interest in these treasures from collectors, jewelers, and enthusiasts around the world.

Among the bidders, Tiffany & Co., the prominent American jewelry house founded in 1837, played a significant role. Recognizing both the intrinsic value and historical significance of the necklace, Tiffany & Co. joined forces with a syndicate to purchase it. The winning bid saw one of the most intricate and historically charged pieces of jewelry change hands and marked the end of the necklace as it was known.

Upon acquiring the necklace, Tiffany & Co. made the business decision to dismantle it, selling the 234 diamonds separately. This act might seem astonishing today, but it was guided by a recognition of the stones' individual value and the desire to create new pieces that would appeal to the tastes of the time. While the original design was lost, the diamonds continued their journey, becoming part of various collections and other jewelry masterpieces.

One of the notable diamonds from the Napoleon Diamond Necklace, a 10-carat cushion-cut gem, found its way into the hands of Marjorie Merriweather Post, a socialite and collector. This particular diamond is now housed at the Smithsonian Institution, where it continues to captivate visitors with its beauty and history.

The decision by Tiffany & Co. to dismantle the Napoleon Diamond Necklace represents a complex moment in the life of this extraordinary artifact. While it led to the loss of a historically significant design, it also allowed the individual gems to take on new forms and stories, thereby continuing to contribute to the ever-evolving narrative of art, luxury, and history in the world of fine jewelry.

The current value of the Napoleon Diamond Necklace is difficult to estimate, given its dismantling and the individual sales of its stones. However, considering the rarity, historical significance, and the exceptional quality of the diamonds, its original worth could easily translate into tens of millions of dollars today.


Cultural Impact

The necklace has been immortalized in paintings and literature and continues to be a symbol of the opulence and grandeur of the French Empire under Napoleon. Its artistic design has also influenced several pieces of modern jewelry.



The Napoleon Diamond Necklace is more than a magnificent piece of jewelry; it's a work of art that connects us with a tumultuous period of history, filled with love, power, ambition, and upheaval. It stands as a testament to the extraordinary craftsmanship of its time and continues to capture the imagination of historians, gemologists, and jewelry enthusiasts alike.

Its story weaves together the lives of emperors and empresses, kings and commoners, and even modern-day collectors, each adding a new chapter to the ongoing legacy of one of the most exceptional necklaces ever created.
