Discovering an unknown historical diamond such as the Farnese Blue happens once in a lifetime. Apart from its beauty, the stone symbolizes 300 years of history.  

Blue has often been identified as the colour of kings and in the 17th and 18th centuries, blue diamonds were viewed as the ultimate royal gift. Like the famous Hope and Wittelsbach diamonds, the Farnese Blue was certainly found in the famed Golconda mines of India, which was the sole source of diamonds until the discoveries in Brazil in the 1720s.

“The Farnese Blue is quite simply an unforgettable diamond.” “Everyone who set their eyes on it was mesmerized by its extraordinary color: the rich blue of the deepest ocean.”

Deputy Chairman of Sotheby’s Europe and Senior International Jewelry Specialist Daniela Mascetti

Given to Elisabeth Farnese, Queen of Spain (1692-1766), the legendary diamond has subsequently passed down through four of the most important royal families in Europe: Spain, France, Italy and Austria.

Witness to 300 years of European history, from the aftermath of the Spanish Succession War to the fall of the Habsburg Empire, the diamond has travelled across the continent for centuries. And all this time, it was kept secretly in a royal casket. Excepting close relatives, and of course the family jewellers, no one knew of its existence.

Tracing the provenance across 300 years

The first historical record dates from 1714-15. In 1714, Philip V (1683-1756), King of Spain married an Italian princess: Elisabeth Farnese (1692-1766). Both were members of illustrious European royal houses.

Philip was one the Sun King’s grandsons. Born a French prince, he became King of Spain in 1700. That year the Spanish line of the House of Habsburg came to an end when King Charles II died in Madrid. Having no children, his immense estates were meant to go to his sister’s descendants. Unfortunately, that sister, the Infanta Marie Thérèse, had married Louis XIV of France. The idea of uniting two of the most powerful states of Europe under a single king was considered too risky, so it was decided that the oldest of Louis XIV and Marie Thérèse’s grandsons, Louis, Duke of Burgundy, would inherit the French Crown. The youngest, Philippe, Duke of Anjou, would become the King of Spain, founding the line of the Spanish Bourbon Kings, which is still on the throne today. Europe, especially Austria and England, found it difficult to accept such a decision, as it still gave France an enormous edge of power. The War of Spanish Succession started in 1701, and would last twelve years. In 1713, the Utrecht Treaty acknowledged the French succession, providing that France and Spain would never be united.

Elisabeth Farnese was the daughter of the Duke of Parma. Her family’s estates were rather small. Furthermore, her father was dead, and her uncle had no sons, so the line was close to extinction. She was 22 years old, not especially pretty, but pleasant enough. The marriage was celebrated in Parma on the 25th of August 1714.

The Spanish finances were in a very bad state, owing to the debts accumulated during the long years of war. In order to provide a suitable dowry for the new queen, the Spanish government sent word to the governors of all the Spanish colonies in the East and West, ordering them to send wedding gifts to Madrid. It took one year to assemble the treasures. In August 1715 the Golden Fleet sailed from Cuba: twelve ships carrying hundreds of gold bullion and a case of enormous emeralds. Unfortunately, after 10 days at sea, a hurricane destroyed most of the fleet in the Gulf of Florida, with only one ship escaping. The story goes that the emeralds were lost in one of the sunken ships. But one diamond found its way to Spain: a pear-shaped blue diamond offered to the new Spanish Queen by the governor of the Philippine Islands.

That provenance is mentioned on a silver plaque which is included in the diamond’s box. It reads in French: “Remarkable blue brilliant. This historical stone was offered by the Philippine Islands to Elisabeth Farnese, Queen of Spain, wife of Philip V, great grandfather of the Comte of Villafranca, current owner of that stone”. The last line gives us the clue of the transmission of the diamond. Comte of Villafranca was the title taken in 1849 by Charles II of Bourbon, ex-king of Etruria, ex-duke of Lucca, ex-duke of Parma (1799-1883). This prince was born on the 22nd of December 1799. Elisabeth Farnese, was his great-great-grandmother. 

The marriage between Elisabeth Farnese and the King of Spain was a happy one. She gave him four sons and three daughters. It seems Elisabeth had a favourite child: the Infant Philip, born in 1720. Being a younger son, there was no chance that he would succeed to the Spanish crown. Elisabeth took it upon herself to find him a crown of his own. The Farnese line being extinct, she organised the succession of her ancestor’s duchy so that Philip would inherit it, which he  finally did in 1745. Four years later, he left Spain to take possession of his small kingdom. It is highly probable that his mother gave him the blue diamond around this time. After all, the stone had been given to the Queen by the islands with which he shared a name. 

From Philip, the first Duke of Parma of the Bourbon line, the stone went to his son, Ferdinand, the second Duke of Parma (1751-1802).

The first years of the 19th century were a very tumultuous time for royal Europe. When Ferdinand died, Napoleon simply annexed the Duchy of Parma.

Ferdinand’s son, Louis (1773-1803) received a small kingdom in compensation. He became King of Etruria with Florence as its capital. His reign was very short as he died in 1803.

His only son, Charles II, at the age of four, inherited the Crown of Etruria, but lost it four years later when Napoleon decided to annex the kingdom. After the fall of the French Emperor in 1814, Charles II should have received his grandfather’s duchy, but the congress of Vienna decided differently. Parma was awarded to Napoleon’s ex-wife, the Empress Marie Louise. In compensation, Charles of Bourbon, received the Duchy of Lucca. He had to wait until the death of Marie-Louise in 1847, to get his ancestral duchy back. And it turned out to be for a very short time. 

1848 was a crucial year in the history of Europe. The entire continent was aflame after the French Revolution of the “Trois Glorieuses”, which marked the end of the Bourbon-Orleans monarchy in France. Parma was not spared. In March 1849, Charles II decided to abdicate and leave the crown to his son, Charles III (1823-1854). He then took the title of Comte de Villafranca. His decision was a wise one. His son Charles III, was murdered in the streets of his capital in 1854.

The Comte de Villafranca lived a very long life, dying in 1883, leaving the blue diamond to his grandson, Robert (1848-1907). After the assassination of his father, he became the last reigning Duke of Parma. He was six years old and the Regency was in the very capable hands of his mother, Duchess Louise (1819-1864) a granddaughter of Charles X of France. But her wise rule was not enough to stop the “Risorgimento”, the unification of Italy was on its way, and in 1859, Duchess Louise and the young Duke Robert left Parma forever. Robert lived most of his life in Austria. Like the other Italian Princes of Tuscany, Modena and Naples, he found refuge in the estates of his cousin, Emperor Franz Joseph (1830-1916). Although he had lost his crown he was still a very rich man. He married twice and each of his wives gave him 12 children. 

One of his sons from his first marriage, Prince Elie (1880-1959), married the Archduchess Maria Anna of Austria (1882-1940) in 1903. In her jewellery inventory, which she wrote herself, Maria Anna of Austria Bourbon-Parma mentioned a diamond tiara, which had been made up out of a diamond belt that had been given to her as a wedding gift by her brothers and sisters-in-law. This tiara had an amazing history as the diamonds set in it came from Queen Marie Antoinette of France (1755-1793), through her daughter, Madame Royale, Duchesse of Angoulême (1778-1851) who had left the tiara to her niece, Louise of France, Duchess of Parma. In her inventory Princess Maria Anna explained that, at one point, the blue diamond was mounted on the tiara.  [A large red leather case with the initials M.A. and a crown, containing a large diamond tiara. This tiara can also be worn as a belt, or a small diadem and a necklace. The blue diamond which is part of it is from the family jewels (list A). This tiara, mounted as a belt, comes as it is from Queen Marie Antoinette and was given by Marie-Thérèse of France, Duchess of Angouleme, Countess of Marnes, to her niece and adoptive daughter, Louise of France, Duchess of Parma, who passed it onto her son, Robert I, Duke of Parma. He gifted it to his wife, the Duchess Maria-Pia. The tiara, or belt, was given to me as a wedding gift, by my brothers and sisters-in-law, the Duchess Maria-Pia’s children].She certainly wore it this way at the resplendent balls for which the Habsburg court was famous. The fall of the Austrian Empire in 1918 marked the end of that fabulous world.  Vincent Meylan, for Sothebys

The diamond was offered for sale by “a princely family” from among Elias’s descendants. The most recent royal owner is not named, but it’s worth noting that Elias’s last surviving daughter, Alicia, died in March 2017.
