How Much is the Hope Diamond Worth Today (History Included)

The Hope diamond is the largest blue diamond in the world that is a part of the Smithsonian National Museum of Natural History collection. Harry Winston gifted it to this prestigious institution in Washington DC in 1958. The Hope diamond’s history & worth is the subject of much controversy and speculation.

This deep blue gem is well-known for its incredible beauty and the curse following its owners throughout its exciting and mysterious history. The first owner was unknown, but it was a part of court jewelry and property of King Louis XIV of France, George IV of England, and Turkish Sultan Abdul Hamid II.

The Hope Diamond

The Hope diamond is the rare and largest natural blue diamond in the world ever discovered, weighted 112 3/16 carats initially. After being cut, this dark greyish-blue diamond of 45.52 carats was classified as a Type IIb diamond with VS1 clarity. In other words, it is almost perfect.

A diamond’s strongly-colored luminescence type is unique and unusually intense. After exposure to UV light, it produces a brilliant red phosphorescence that stays unchanged even after switching off the light source.

It is famous for its unique cushion antique brilliant cut, and one faceted girdle. The diamond’s current name comes from the family who owned this gem from 1824, but it is known for a few other names, like:

  • The King’s Jewel (Le Bijou Du Roi)
  • The Blue of France (Le Bleu de France)
  • Tavernier Blue

The Hope diamond has a bad reputation as a cursed gem since many owners had a troubled life and even tragic end. The beautiful diamond Heart of the Ocean you can see in the Titanic movie is not an existing gem. However, it is based on the famous Hope diamond.

Hope Diamond History

Hope Diamond History

Indian period

The legend says this diamond is cursed, and many people shy away from it. On the other hand, others enjoy its beauty and don’t care about rumors.

The triangular 112 3/16-carat, beautifully violet Hope diamond was found at an Indian mine. Even though some believe it was the Kollur mine in Golconda, no one can confirm that, and the exact location stayed uncertain.

The diamond’s official history started once Jean-Baptiste Tavernier, a traveling French merchant, bought it in the diamond market in Golconda and brought it to Europe.

French period

In 1669, Jean-Baptiste Tavernier sold the diamond to King Louis XIV with 1,000 other gems. He ordered the court jeweler to cut the gem and reduce it to 67.125 carats in 1678. Its official name became Violet de France (Blue Diamond of the Crown of France, French Blue).

Jeweler Sieur Pitau spent two years perfecting the diamond and set it in a gold cravat pin. Still, King Louis XV ordered court jeweler Andre Jacquemin to reset it again and transform it to a pendant for the Toison D’Or (Royal Order of the Golden Fleece) in 1749.

After French Revolution, the Crown jewels of France were stolen, including the famous diamond, in September 1792. After another re-cutting, the stone came to England, where its trace was lost until 1812.

Sultan Abdul Hamid 1908

Pierre Cartier 1910
Evalyn Walsh McLean 1911

British period

The merchant Daniel Eliason had the diamond cut in 1824 and sold it to London banker Thomas Hope. After his death, his younger brother Henry Philip Hope inherited the gem. That was a period when the stone got its new name that has stayed until today.

The new heir became Henry Thomas Hope after Henry Philip died in 1839. He let the diamond be exhibited at the Great Exhibition in London in 1851 and then the Exposition Universelle in Paris in 1855.

His adopted daughter Henrietta gave the diamond to his grandson, Henry Francis Hope Pelham-Clinton, in 1887. After the family bankruptcy in 1897, he resold the gem to London jeweler Adolph Weil in 1902 for £29,000.

American period

It is known that American broker Simon Frankel bought the Hope diamond for $250,000. He brought the stone to New York, where its value was evaluated to only $141,032. After being in the hand of one sultan, Pierre Cartier became an owner in 1910.

After long and detailed negotiations, he sold the gem to Evalyn Walsh McLean for $300,000 in 1911. Financially speaking, this diamond wasn’t a positive transaction for Cartier because he took a loss after legal fees. However, that trade paid off in the long run and ranked Cartier among the top respected goldsmiths.

After Evalyn’s tragic life and final death in 1947, her entire jewelry collection, including the famous gem, passed to Harry Winston, a New York diamond merchant, in 1949. He exhibited it during the ten years, including the Court of Jewels tour.

It is unclear whether the legend of the cursed diamond affected his decision, but Harry donated the Hope to the Smithsonian Institute on November 10, 1958. Interestingly, he wrapped it in the package and sent it to the Smithsonian by post.

With up to seven million annual admirers, the Hope diamond is the museum’s premier attraction and the second most visited art item worldwide, right after the Mona Lisa.
