How Much Is The Hope Diamond Worth Today?

The Smithsonian National Museum of Natural History has the Hope diamond, which is the largest blue-colored diamond in the world. It was gifted to Washington DC’s prestigious institution by Harry Winston in 1958. Much controversy surrounds the history and value of the Hope diamond.

This deep blue gem is famous for its beauty and its curse that has followed its owners through its fascinating and mysterious history. Although the original owner is unknown, it was part of court jewelry, owned by King Louis XIV, George IV, and Sultan Abdul Hamid II.

The Hope diamond, weighing 112 3/16 carats at its initial weight, is the largest and most rare natural blue diamond ever discovered. This dark greyish-blue 45.52 carat diamond was cut and classified as a Type IIb with VS1 clarity. It is also almost perfect.

The unique, intensely colored luminescence of a diamond is unusual and rare. It produces a bright red phosphorescence after exposure to UV light. This phosphorescence remains unchanged even after the light source is switched off.

It is known for its unique antique cushion cut and one-faceted girdle. Although the diamond’s current name is from the family that owned it since 1824, there are a few other names for this gem, such as:

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

Since many of its owners suffered a difficult life and ended up in a tragic place, the Hope diamond has earned a bad reputation for being a cursed gem. It is not an actual gem that you see in the Titanic movie, the beautiful Heart of the Ocean diamond. It is however based on the Hope diamond.

Hope Diamond History

Hope Diamond History

Indian Period

Legend has it that this diamond is cursed and people avoid it. Others, on the other hand love its beauty and don’t care about rumors.

An Indian mine found the triangular 112 3/16 carat, beautiful violet Hope diamond. Although some claim it was the Kollur Mine in Golconda, none can confirm this and the exact location remains unknown.

Jean-Baptiste Tavernier (a French traveler merchant) bought the diamond in Golconda’s diamond market and took it to Europe.

French Period

Jean-Baptiste Tavernier, a 1669 merchant, sold the diamond to King Louis XIV along with 1,000 other gems. In 1678, he ordered that the court jeweler cut the gem to reduce its size to 67.125 cars. It was officially named Violet de France (Blue Diamond of Crown of France, French Blue).

Two years ago, jeweler Sieur Pitau perfected the diamond. He then set it in a gold-cravat pin. King Louis XV still ordered Andre Jacquemin, a court jeweler, to reset the diamond and make it a pendant for the Toison D’Or in 1749.

The Crown jewels of France, including the famous and cherished diamond, were taken in September 1792 by the French Revolution. The stone was returned to England after another re-cutting. Its trace was lost until 1812.

Daniel Eliason, a merchant, cut the diamond in 1824 and sold it off to Thomas Hope, a London banker. Henry Philip Hope, his younger brother, took the gem after his death. This was the time , the stone received its new name which has remained until today.

Henry Thomas Hope became Henry Philip Hope in 1839, after Henry Philip had died. The diamond was displayed at the Great Exhibition of London in 1851, and the Exposition Universelle Paris in 1855.

In 1887, his adopted daughter Henrietta gifted the diamond to Henry Francis Hope Pelham -Clinton. He resold his gem to Adolph Weil, a London jeweler, in 1902 for PS29,000.

American Period

Simon Frankel, an American broker, purchased the Hope diamond for $250,000. The stone was brought to New York by Simon Frankel, an American broker. Its value was only $141,032. Pierre Cartier, after the stone had been in the hands of one Sultan, became its owner in 1910.

He sold the gem to Evalyn McLean in 1911 for $300,000. This transaction was not a good one for Cartier financially. He lost his legal fees. But, the trade was a success and Cartier was ranked among the most respected goldsmiths.

Evalyn died in tragic circumstances in 1947. Her entire jewelry collection was passed to Harry Winston in 1949. Winston is a New York diamond merchant. It was displayed during the ten-year period, which included the Court of Jewels tour.

Although it is not clear whether Harry was motivated by the legend of the cursed diamant, he donated the Hope to Smithsonian Institute on November 10, 1958. He wrapped the Hope in a package and sent it by mail to the Smithsonian.

The museum’s most popular attraction, the Hope diamond, is a favorite of up to 7 million people annually. It is also the second most-visited art item in the world, just after the Mona Lisa.
