The Hope Diamond: A Jewel of Mystery and Majesty
The Hope Diamond has passed through the hands of a French gem trader, the Sun King, a Dutch banker, an American heiress, and the US postal service before reaching its current home in the Smithsonian Institution. At 45.52 carats, it is the most famous diamond in the world — and its cushion antique brilliant cut connects it directly to the cutting traditions found in antique diamond rings today.
Where Did the Hope Diamond Come From?
The French gem merchant Jean-Baptiste Tavernier acquired a roughly 115-carat blue diamond during his sixth voyage to India between 1664 and 1668. The stone — triangular, with a crude Mogul-style cut — was most likely mined at the Kollur mine in Golconda, southern India, though the specific mine has never been conclusively confirmed. Tavernier described the colour as "a beautiful violet."
Tavernier sold the diamond to Louis XIV in 1668 or 1669 for 220,000 livres. The King's court jeweller recut it in 1673 to approximately 67 carats, creating the stone known as the French Blue. Smithsonian researchers Francois Farges and Jeffrey Post discovered through computer modelling that the French Blue was mounted on a stick set in gold so that light passed through specially angled back facets, producing a brilliant gold sun effect — an emblem of Louis XIV's identity as the Sun King.
How Was the Diamond Stolen and Transformed?
The French Blue was stolen in September 1792 during the French Revolution, after the Crown Jewels had been confiscated in 1791 and put on public display. The Revolution also scattered Marie Antoinette’s personal diamonds, smuggled to Vienna before her execution — a parallel dispersal of French royal jewels whose story rivals the Hope Diamond’s own. The stone vanished for twenty years.
A blue diamond weighing approximately 45.5 carats resurfaced in London in 1812 in the possession of diamond merchant Daniel Eliason. Jeweller John Francillon documented it in a memo dated 19 September 1812 — just two days after the expiration of the twenty-year statute of limitations for crimes committed during the Revolution. The timing was almost certainly deliberate: whoever had recut the French Blue into a smaller stone had waited precisely long enough to avoid prosecution.
| Date | Event | Weight |
|---|---|---|
| 1668 | Tavernier acquires stone in India | ~115 carats |
| 1673 | Recut as the French Blue for Louis XIV | ~67 carats |
| 1792 | Stolen during French Revolution | ~67 carats |
| 1812 | Resurfaces in London, recut | ~45.5 carats |
| 1988 | GIA measurement at Smithsonian | 45.52 carats |
Who Were the Hopes?
Henry Philip Hope (1774–1839) was a wealthy Anglo-Dutch banker and gem collector. The diamond was catalogued in his 1839 collection, giving it the name it has carried ever since. The stone passed through the Hope family until it was sold at auction in 1901–1902, beginning a chain of ownership that would bring it to America.
Is the Hope Diamond Curse Real?
The curse is a fabrication. Smithsonian scholar Richard Kurin, in his book Hope Diamond: The Legendary History of a Cursed Gem (2006), traced the legend to early twentieth-century journalists and the jeweller Pierre Cartier, who used the curse narrative as a sales tool when offering the diamond to American heiress Evalyn Walsh McLean in 1911.
Cartier succeeded. McLean purchased the diamond for $180,000 — equivalent to approximately $6 million today — and wore it publicly for the rest of her life, lending it to friends and even letting her Great Dane wear it. McLean died in 1947. Her jewels were sold to Harry Winston in 1949.
How Did the Hope Diamond Reach the Smithsonian?
Harry Winston acquired the diamond in 1949 and displayed it on a nationwide tour before making one of the most audacious decisions in jewellery history: he donated it to the Smithsonian Institution in November 1958, sending it by registered US mail in a plain brown paper package. The postage cost $145.29. The insurance value was $1 million.
The Hope Diamond has been on permanent display at the Smithsonian's National Museum of Natural History ever since, in the Janet Annenberg Hooker Hall of Geology, Gems, and Minerals. It draws millions of visitors each year.
What Makes the Hope Diamond Scientifically Unusual?
The GIA measured the Hope Diamond at 45.52 carats in 1988. Its deep blue colour comes from traces of boron within the crystal structure — a rare impurity that gives Type IIb diamonds their distinctive hue. The cut is a cushion antique brilliant — a style that shares the deep pavilions and small table facets of the old mine cuts found in Georgian and Victorian rings.
Most distinctively, the Hope Diamond exhibits red phosphorescence under ultraviolet light — it glows red for several seconds after UV exposure, a phenomenon the Smithsonian describes as "extremely unusual for diamonds." This property has been used to help trace its connection to the French Blue through spectroscopic analysis.
What Connects the Hope Diamond to Antique Rings?
The Hope Diamond's cushion antique brilliant cut belongs to the same family of cutting styles found in antique rings from the Georgian and Victorian periods. Old mine cut diamonds — the most common antique diamond cut — share the Hope Diamond's deep pavilions, small table facets, and emphasis on fire (coloured light flashes) over brilliance (white light return). These stones were cut by hand to maximise beauty under candlelight, not under the fluorescent tubes of a modern laboratory.

The Hope Diamond's four-century journey from Indian mine to Smithsonian display case is extraordinary, but every antique ring carries its own chain of ownership — its own sequence of hands it has passed through, occasions it has marked, and stories it has witnessed. That shared quality — a tangible connection to the past through an object you can hold — is what draws collectors to antique jewellery.

Frequently Asked Questions
How big is the Hope Diamond?
The Hope Diamond weighs 45.52 carats, as measured by the GIA in 1988. It is a cushion antique brilliant cut — the same family of cutting styles found in Georgian and Victorian diamond rings. Its deep blue colour comes from traces of boron in the crystal structure.
Where is the Hope Diamond now?
The Hope Diamond is on permanent display at the Smithsonian Institution's National Museum of Natural History in Washington, D.C., in the Janet Annenberg Hooker Hall of Geology, Gems, and Minerals. Harry Winston donated it in November 1958.
Is the Hope Diamond curse real?
The curse is a fabrication traced to early twentieth-century journalists and the jeweller Pierre Cartier, who used the narrative as a sales tool. Smithsonian scholar Richard Kurin debunked it definitively in his 2006 book. Most documented "curse victims" either prospered after owning the diamond or suffered misfortunes unrelated to it.
How did the Hope Diamond get its name?
The diamond is named after Henry Philip Hope (1774–1839), a wealthy Anglo-Dutch banker and gem collector who catalogued it in his 1839 collection. The stone passed through the Hope family until it was sold at auction in 1901–1902.
Was the Hope Diamond really sent by post?
Harry Winston donated the Hope Diamond to the Smithsonian in November 1958 by registered US mail in a plain brown paper package. The postage cost $145.29, and the package was insured for $1 million. The package was delivered by a regular mail carrier.
Why is the Hope Diamond blue?
The deep blue colour comes from traces of boron within the diamond's crystal structure, making it a Type IIb diamond — a classification that accounts for fewer than 0.1% of all natural diamonds. Under ultraviolet light, the Hope Diamond also exhibits an unusual red phosphorescence, glowing red for several seconds after UV exposure.
