, the equivalent of 147 kilograms of pure gold. In a newly published historical novel, The French Blue, gemologist and historian Richard W. Wise proposed that the patent of nobility granted Tavernier by Louis XIV was a part of the payment for the Tavernier Blue. According to the theory, during that period Colbert, the king's Finance Minister, regularly sold offices and noble titles for cash, and an outright patent of nobility, according to Wise, was worth approximately 500,000 livres making a total of 720,000 livres, a price much closer to the true value of the gem. There has been some controversy regarding the actual weight of the stone; Morel believed that the 112 carats stated in Tavernier's invoice would be in old French carats, thus 115.28 metric carats.

The king had the stone set on a cravat-pin. According to one report, Louis ordered Pitau to "make him a piece to remember", and Pitau took two years on the piece, resulting in a "triangular-shaped 69-carat gem the size of a pigeon's egg that took the breath away as it snared the light, reflecting it back in bluish-grey rays." It was set in gold and was supported by a ribbon for the neck which was worn by the king during ceremonies.

A likely scenario is that the French Blue or sometimes also known as the Blue Diamond was "swiftly smuggled to London" after being seized in 1792 in Paris. But the exact rock known as the French Blue was never seen again, since it almost certainly was recut during this decades-long period of anonymity, probably into two pieces, and the larger one became the Hope Diamond. One report suggested that the cut was a "butchered job" because it sheared off 23.5 carats from the larger rock as well as hurting its "extraordinary lustre." It had long been believed that the Hope Diamond had been cut from the French Blue until confirmation finally happened when a three-dimensional lead

While the diamond had disappeared for several decades, there were questions whether this recovered diamond in Britain was the same as had belonged to the French king, but subsequent scientific investigation in 2008 confirmed "beyond reasonable doubt" that the Hope Diamond and that owned by the French king were, in fact, the same gemstone in the sense that the Hope Diamond had been cut from the same material as the French Blue.

A conflicting report is that the king's debts were "so enormous" that the diamond was likely sold through "private channels." In either case, the blue diamond was not retained by the British royal family.

There was a report that the gemstone was bought by a wealthy London banker named Henry Thomas Hope for either $65,000 or $90,000. After falling under the ownership of the Hope family, and remaining in its possession for more than half a century, it came to be known officially as the "Hope Diamond". There was a report that Eliason may have been a "front" for Hope, acting not as a diamond merchant but rather as an agent to acquire the diamond for the banker. In 1839, the Hope Diamond appeared in a published catalog of the gem collection of Henry Philip Hope who was a member of the prominent Anglo-Dutch banking family. The stone was set in a fairly simple medallion surrounded by many smaller white diamonds, which he sometimes lent to Louisa Beresford, the widow of his brother, his nephew Henry Thomas Hope, for society balls

. When Hope died on December 4, 1862, his wife Anne Adele inherited the gem, but feared that the profligate lifestyle of her son-in-law, the 6th Duke of Newcastle, might cause him to sell the Hope properties. Upon Adele's death in 1884, the entire Hope estate, including the Hope diamond, was entrusted to Henrietta's younger son, Henry Francis, on the condition that he change his surname when he reached legal majority.

She later claimed she had worn the diamond at social gatherings and had an exact replica made for her performances, but he claimed otherwise. Lord Francis lived beyond his means, and it eventually caught up with him, leading to marriage troubles, financial reverses, and he found that he had to sell the diamond. In 1896, his bankruptcy

Lord Francis sold the diamond for £29,000 (£ as of ), to Adolph Weil, a London jewel merchant. Weil later sold the stone to a New York-based or London-based (accounts differ) diamond dealer Simon Frankel, who took it to New York. There, it was evaluated to be worth $141,032 (equal to £28,206 at the time).

United States (1902-present)

Accounts vary about what happened to the diamond during the years 1902-1907; one account suggested that it lay in the Frankel safe during these years while the jewelers took it out periodically to show it to wealthy Americans; a rival account, probably invented to help add "mystery" to the Hope Diamond story, suggested that some persons had bought it but apparently sold it back to Frankel. There were reports in one story in The New York Times

of several owners of the gem, perhaps who had bought it from Frankel and owned it temporarily who met with ill-fortune, but this report conflicts with the more likely possibility that the gem remained in the hands of the Frankel jewelry firm during these years. Like many jewelry firms, the Frankel business ran into financial difficulties during the depression of 1907 and referred to the gem as the "hoodoo diamond."

In 1908, Frankel sold the diamond for $400,000 to a Salomon or Selim Habib, a wealthy Turkish diamond collector, reportedly in behalf of Sultan Abdul Hamid

 of Turkey; however, on June 24, 1909, the stone was included in an auction of Habib's assets to settle his own debts, and the auction catalog explicitly stated that the Hope Diamond was one of only two gems in the collection which had never been owned by the Sultan. A contrary report, however, suggested that Sultan Hamid did own the gem but ordered Habib to sell it when his throne "began to totter." Habib reportedly sold the stone in Paris in 1909 for $80,000. The Parisian jewel merchant Simon Rosenau bought the Hope Diamond for 400,000 francs and resold it in 1910 to Pierre Cartier

 and her husband in 1910, Cartier was a consummate salesman who used an understated presentation to try to entice the Washington-based socialite. He described the gem's illustrious history to her while keeping it concealed underneath special wrapping paper. The suspense worked: McLean became impatient to the point where she suddenly requested to see the stone. And she recalled later that Cartier "held before our eyes the Hope Diamond." Nevertheless, she initially rejected the offer perhaps because of her distaste for the Hope family's old setting. Cartier had it reset, and she found the stone much more appealing in this new modern style, and stories about its supposed "cursed" effects may have helped persuade her and her husband to buy it. There were conflicting reports about the sale in the New York Times; one account suggested that the young McLean couple had agreed to purchase the diamond, but after having learned about its unfortunate supposed history, the couple had wanted to back out of the deal since they knew nothing of the "history of misfortunes that have beset its various owners."
The brouhaha over the diamond's supposed "ill luck" prompted a worried editor of The Jewelers' Circular-Weekly to write:
The tenuous deal involved wrangling among attorneys for both Cartier and the McLeans, but finally, in 1911, the couple bought the gem for over $300,000, although there are differing estimates of the sales price at $150,000 and $180,000. An alternative scenario is that the McLeans may have fabricated concern about the supposed "curse" to generate publicity to increase the value of their investment.

A description was that the gemstone "lay on a bed of white silk and surrounded by many small white diamonds cut pear shaped". The new setting was the current platinum framework surrounded by a row of sixteen diamonds which alternated between Old Mine Cut and pear-shaped variants. Ms. McLean wore it to a "brilliant reception" in February 1912 when it was reported that it was the first time it had been worn in public since it had "changed owners." She would "sport the diamond at social events" and wore it numerous social occasions that she had organized.
There were reports that she misplaced it at parties, deliberately and frequently, and then make a children's game out of "finding the Hope", and times when she hid the diamond somewhere on her estate during the "lavish parties she threw and invite guests to find it." The stone prompted elaborate security precautions:
But the stone was not stolen during their ownership. When Ms. McLean died in 1947, she bequeathed the diamond to her grandchildren through a will which insisted that her former property would remain in the custody of trustee

. Starting in September 2009, the 45.52 carats (9.1 g) diamond will be exhibited as a stand-alone gem with no setting. It was removed from its setting for cleaning from time to time, but this is the first time it will be on public view by itself. Previously it had been shown in a platinum setting, surrounded by 16 white pear-shaped and cushion-cut diamonds, suspended from a chain containing forty-five diamonds.

The Hope returned to its traditional setting in late 2010.

On November 18, 2010, the Hope Diamond was unveiled and displayed at the Smithsonian in a temporary newly-designed necklace called "Embracing Hope," created by the Harry Winston firm. Three designs for the new setting, all white diamonds and white metal, were created and the public voted on the final version. The Hope Diamond also is resting on a new dark blue neck form, which the Harry Winston firm commissioned from display organization, Pac Team Group. Previously, the Hope Diamond had been displayed as a loose gem since late summer of 2009 (see above image) when it was removed from its former Cartier-designed setting. A Smithsonian curator described it as "priceless" because it was "irreplaceable", although it was reported to be insured for $250 million. In 2012 the diamond will be returned to its historic setting, and the current necklace will be implanted with another diamond worth "at least a million dollars," and the necklace with the new diamond will be sold to benefit the Smithsonian.

In 2010, the Smithsonian licensed its gem and jewelry collection to create a "line of bracelets, brooches and other baubles" to be sold on the TV shopping network QVC; the jewelry line will not have real diamonds, but will serve as costume jewelry with semiprecious stones, and benefits the museum by being an additional source of revenue.

 newspaper article in 1888 described the supposedly lurid history of the Hope Diamond, including a claim that it was "said once to have formed the single eye of a great idol", as part of a confused description that also claimed that its namesake owner had personally "brought it from India", and that the diamond's true color was "white, [although] when held to the light, it emits the most superb and dazzling blue rays." An article entitled "Hope Diamond Has Brought Trouble To All Who Have Owned It" appeared in the Washington Post in 1908. An additional account of the Hope Diamond's "cursed origins" was a fanciful and anonymously written newspaper article in 1909.

 temple where it had been set as one of two matching eyes of an idol, and the temple priests then laid a curse on whoever might possess the missing stone. Largely because the other blue diamond "eye" never surfaced, historians dismissed the fantastical story. The stories generally do not bear up to more pointed examination; for example, the legend that Tavernier's body was "torn apart by wolves" is inconsistent with historical evidence which shows that he lived to 84 and died of natural causes.

It is possible that the overblown story of the curse, possibly fueled by Cartier and others, may have caused some hesitation on the part of the prospective buyers, the McLeans, around 1911. When a lawsuit between buyer and seller erupted about the terms of the deal, newspapers kept alive reports of the diamond's "malevolent influence" with reports blaming like this one, which blamed the stone's "curse" on having caused, of all things, the lawsuit itself:

 who had supposedly killed various members of his court for the stone (despite the annotation in Habib's auction catalog). Even jewelers who may have handled the Hope Diamond were not spared from its reputed malice: the insanity and suicide of Jacques Colot, who supposedly bought it from Eliason, and the financial ruin of the jeweler Simon Frankel, who bought it from the Hope family, were linked to the stone. But although he is documented as a French diamond dealer of the correct era, Colot has no recorded connection with the stone, and Frankel's misfortunes were in the midst of economic straits that also ruined many of his peers. The legend includes deaths of numerous other characters who had been previously unknown: Diamond cutter Wilhelm Fals, killed by his son Hendrik, who stole it and later committed suicide; Francois Beaulieu, who received the stone from Hendrik but starved to death after selling it to Daniel Eliason; a Russian prince named Kanitowski, who lent it to French actress Lorens Ladue and promptly shot her dead on the stage, and was himself stabbed to death by revolutionaries; Simon Montharides, hurled over a precipice with his family. However, the existence of only a few of these characters has been verified historically, leading researchers to conclude that most of these persons are fictitious.

In 2007, an important discovery was made which enabled a slew of activity to help scientists, historians and gemologists further explore the history of the Hope Diamond, as well as create replicas of the larger pieces, from which it had been cut, believed to have been owned by eighteenth-century French monarchs. A lead cast of the French Blue diamond was discovered in the gemmological collections of the National Museum of Natural History

The lead cast of the French Blue, itself, has a history. It had been catalogued at the French museum in 1850 and was provided by a prominent Parisian jeweler named Charles Archard who lived during the same generation as René Just Haüy
René Just Haüy

, who died in 1822. Most likely, the lead cast was made near 1815, since that was the year that similar entries from the 1850 catalogue had been made. The model was accompanied by a label stating that the French Blue was in the possession of a person known as "Mr. Hoppe of London". Other archives at the Muséum suggests that Achard had Mr. Hope as a good customer for many long years, particularly for blue gems.

These findings have helped investigators piece together what may have happened during the rock's anonymous years during the several decades following 1792. According to one line of reasoning, the first "Hope" to have the "Hope Diamond"––Henry Phillip Hope––might have possessed the French Blue that he had acquired some time after the 1792 robbery in Paris, perhaps around 1794-1795, when the Hopes were believed to have left Holland for London to escape Napoleon's armies. At about the same time, Cadet Guillot, who may have been one of the thieves to have stolen the Golden Fleece, arrived in London. This places Mr. Hope and Mr. Guillot in London at the same time. According to a late nineteenth century historian named Bapts, a contract was made between Cadet Guillot and a French aristocrat named Lancry de la Loyelle, in 1796, to sell the 107 carats (21.4 g) spinel
Spinel

-dragon of the Golden Fleece. According to this line of reasoning, in 1802 Hope sold his assets, and the continental blockade by Napoleon led the Hope's bank into a serious financial crisis by 1808, and the crisis peaked during the winter of 1811-1812 This put Mr. Hope in a financial bind. There is a possibility that, given his financial predicament, Hope pawned the French Blue to jewel merchant Daniel Eliason to get much-needed cash when the British currency, sterling
Pound sterling
The pound sterling , commonly called the pound, is the official currency of the United Kingdom, its Crown Dependencies and the British Overseas Territories of South Georgia and the South Sandwich Islands, British Antarctic Territory and Tristan da Cunha. It is subdivided into 100 pence...

, was highly depreciated. This is consistent with the entry in Eliason's records about having the stone in 1812. However, the diamond's owners may have felt pressure to recut the stone quickly to disguise its identity, since if the French government had learned of its existence, it may have sued the owners for repossession. Regardless of whether Mr. Hope had lost possession or kept it during these years, by 1824 it was again in his possession. It was around this time that Eliason died; Hope's financial situation has been restored thanks to efforts by the Barings, who saved the Hope bank in the difficult financial years of 1812-1820. Accordingly, if this is correct, then the lead cast of the French Blue and the "Hope" diamond are likely to have been created in the same workshop, possibly in London, and probably a little before 1812.
The lead cast had important ramifications since it gave enough information to curators at the French museum to commission the first exact replicas of both the Tavernier and French Blue diamonds using a material which simulates diamonds called cubic zirconia

 and the Great Sapphire of Louis XIV, a Moghul-cut sapphire of 135.7 carats (27.1 g). Artisans recreated the elaborate piece known as the Golden Fleece of King Louis XV of France, which is arguably the most fabulous work in the history of French jewelry; this happened from 2007–2010. The original Golden Fleece of the Color Adornment, created in 1749 by royal jeweler Pierre-André Jacqumin, was stolen and broken in 1792. The reassembled jewel contained the French Blue and the Bazu diamonds, as well as the Côte de Bretagne spinel and hundreds of smaller diamonds. Three years of work were needed to recreate this jewel, and it required exacting and precise skill which revealed not only the skill of today's lapidaries, but the skill of its original eighteenth-century designers. The reconstructed jewel was presented by Herbert Horovitz, with François Farges of the French museum in attendance, at the former Royal Storehouse in Paris on June 30, 2010, which was the same site where the original had been stolen 218 years before.

Additional recreations were made possible by new discoveries. A previously-unknown drawing of the Golden Fleece was rediscovered in Switzerland

 in the 1980s, and two blue diamonds that had ornamented the jewel were found as well, and these recent findings enabled artisans to recreate a copy of the emblem. It led to the construction, using cubic zirconia, of a piece that almost exactly resembles the mythic French Blue 69 carats (13.8 g) masterpiece.
The emblem has another great blue diamond, which was later named "the Bazu" in reference to a dealer who reportedly had sold it to Louis XIV in 1669. This Bazu diamond was recut in 1749 as a baroque cushion weighing 32.62 carats (6.5 g). The 1791 inventory mentioned that the Bazu was "light sky blue", which is consistent with the fact that the Golden Fleece of the Color Adornment was made of a variety of great colored gems. Based on documents kept in a private collection, it could be shown that this particular diamond was not hexagonal-shaped, as some historians had previously thought, but was in a shape best described as "rounded squared", similar to the so-called Régent diamond
Regent Diamond
The Regent Diamond is a diamond which is on display in the Louvre.

. There is a report that a curator from the French museum

 will assert that the hexagonal cut from the Bazu is inconsistent historically and gemologically. The Bazu stone referred to another version of Louis XV’s great Golden Fleece, made out of blue sapphires instead of blue diamonds. According to one view, this version appears to have never been manufactured but only suggested to the king as an alternative to the effective final version, bearing two blue diamonds. Nevertheless, replicas of both blue diamonds were cut by Scott Sucher using cubic zirconia, one being colored deep–blue and the other light–blue.

The emblem had a third great gem known as The Côte de Bretagne dragon. Its replica was based on a wax likeness sculpted by Pascal Monney, who had based his recreation from three-dimensional scaled pictures of the original object which had been made by French artist François Farges; Farges, in turn, had seen the original objects displayed at the Louvre's Galerie d’Apollon.

.

The 500-plus remaining replicas of diamonds were cut from cubic zirconia using a baroque cushion cut. Colors were used to recall the original artwork: red for the flames, and yellow for the fleece, and in keeping with the original work, the materials used were initially colorless but were painted in the same fashion used by the artist Jacqumin when the original Golden Fleece was completed in 1749. Since the original was most likely made out of gold plated with silver, a choice was made to use a matrix mostly made out of 925-grade silver to keep costs under control without compromising quality. A number of different artists helped with this project:
  • The silver matrix was carved by Jean Minassian of Geneva who used historical drawings of the delicate three-dimensional elements of the dragon's wings and tail as well as the palms around which the dragon is suspended.

  • Casts were made by Andreas Altmann. This will allow even more copies to be made in the future.

  • Amico Bifulci gilded parts of the matrix to recreate the elegant original gold and silver arrangement of the original.


All stones were set according to 18th century techniques. Finally, a luxury box containing the Golden Fleece was recreated by Frédéric Viollet using crimson-colored Moroccan leather. The box was gilded by Didier Montecot to the arms of Louis XV, using the king’s original iron stamp made by the Simier house. A dark red cramoisi ribbon, made of crimson satin moire, holds the jewel inside the box.
