Crown of Louis XV Of about 20 documented royal crowns of the
Ancien Régime, the only surviving one from the destructions of 1590 and 1793 is the
crown of Louis XV. The king had the Regent Diamond set in the lower part of the
fleur-de-lis in the front of his crown, while eight of the famous
Mazarin diamonds that the cardinal had bequeathed to the French Crown are set in the other seven fleur-de-lis and in the circlet of the crown. Diamonds and colored gemstones are set between two rows of pearls on the circlet and are also set into the four arches that rise behind the fleur-de-lis and the eight ornamental points between the fleur-de-lis. At the junction of these four arches is a small pedestal surrounded by two rows of small diamonds on either side of a row of small pearls. Eight larger diamonds set between this pedestal and the arches give the effect of a sunburst when the crown is viewed from above. On the pedestal rises a double fleur-de-lis formed of nine large diamonds, including the Sancy Diamond which forms the central upper petal of this double fleur-de-lis. The gold brocade cap which lines the crown is also ornamented with large diamonds. Since the Middle Ages, and previous to the making of this crown, the crowns of French kings were adorned with gemstones like on the
crown of Charlemagne or the crown of
Saint Louis, sometimes called the
Sainte Couronne. But some of the most valuable precious stones could be removed from them, since it was traditional for a French king to bequeath his crown to the treasury of the Abbey, now
Basilica of St Denis, on their deaths. This crown was also bequeathed to Saint Denis on the death of Louis XV, but not before the diamonds had been replaced with crystals, and it is on display presently in the Louvre, similarly set with crystals.
Crown of Napoleon I The
crown of Napoleon was made by the jeweller
Martin-Guillaume Biennais with antique
cameos for the coronation of the Emperor in 1804. His gilded crown of laurels was destroyed in 1819 by
Louis XVIII with the one of
Empress Josephine, the
orb and the eagle sceptre. His coronation throne is at the
Louvre and the coronation ring of
Empress Josephine at the
Château de Malmaison.
Crown of Empress Eugénie The
crown of Empress Eugénie was created in 1855 by Gabriel Lemonnier for the World's fair, like that of the Emperor which was destroyed in 1887. But
Napoleon III finally chose not to be crowned. Her
diadem by the same jeweller is on display in the
Louvre with a large diamond brooch by Alfred Bapst bearing two big
Mazarin stones, as well as a large corsage diamond knot and a pearl and diamond shoulder brooch, both by François Kramer. On October 19, 2025, this piece was involved in a robbery at the Louvre but was recovered in damaged condition. Louvre president
Laurence des Cars described the ability to restore the crown, which had been "badly damaged," as "delicate, but possible."
Coronation sword '', the legendary sword of
Charlemagne, in the
Louvre, Paris. The sword used during the coronation of the kings of France is displayed at the Louvre museum with its 13th-century
scabbard, apart from the crown jewels. In the first part of the celebration, the king received the insignia of knighthood, consisting of spurs and the sword. Throughout the rest of the ceremony, the sword was entrusted to the "Connétable", who held it with the blade pointing upwards. The treasury of Saint-Denis possessed several medieval swords including the one of
Saint Louis. According to legend the coronation sword is "
Joyeuse", Charlemagne's sword. Its unusual build and ornamentation makes it difficult to date, but the parts probably date back from the 10th to 13th centuries. Some believe it might be much older, even manufactured before
Charlemagne's reign. The coronation swords of
Napoleon I and
Charles X also were preserved in the Louvre museum, although the first was transferred to the
Palace of Fontainebleau with most of the preserved liturgical instruments and robes of the imperial ceremony and the latter stolen in 1976.
Coronation spurs Some elements of the 12th to 16th
centuries spurs were partially replaced for the coronation of
Napoleon I.
Sceptre of Charles V on the sceptre of
Charles V, 14th c.,
Louvre. One of the few surviving pieces of the medieval French crown jewels is the sceptre that
Charles V had made for the future coronation of his son,
Charles VI, currently on display in the
Louvre. It is over five feet long, and at the top is a lily supporting a small statuette of Charlemagne. This evocation of Charlemagne may also explain why this sceptre was included in the imperial regalia of Napoleon I. The sceptre of
Dagobert I was stolen in 1795 during the Revolution.
Main de Justice (Hand of Justice) . A typically French type of sceptre is the
Main de Justice (Hand of Justice), which has as its
finial an ivory
Hand of God in a blessing gesture was recreated in 1804 for Napoleon I The addition of cameos and other medieval gemstones, like the 12th-century ring of
Saint Denis which surrounds the junction of the finial and the replaced rod, represents a deliberate 19th-century anachronism. Another sceptre, the Baton of Guillaume de Roquemont, and the ring of
Saint Louis are at the
Louvre.
Brooch of Saint Louis The collection keeps as well the 14th-century brooch or
fermail said of
Saint Louis, a large diamond shaped
fibula bearing a fleur-de-lis in precious stones, which was used to hold the coronation's robe.
Serpentine paten of
serpentine with inlaid gold fish, 1st century BCE or CE, with 9th-century mounts,
Louvre.] The serpentine
paten said to be of
Abbot Suger of the 1st century BC or AD, associated with the
Cup of the Ptolemies, was used at the coronation of queens and keeps its gem-studded gold Carolingian mountings of
Charles the Bald.
Famous diamonds Among the most famous diamonds preserved in the collection and now kept in the Apollo Gallery of the
Louvre are the
Sancy Diamond, which once had been part of the pre-Commonwealth Crown Jewels of England, the Hortensia pink diamond cut in 1678 for
Louis XIV and above all the
Regent Diamond. The treatment of the Regent Diamond epitomised the attitude of the French Royal Family to the Crown Jewels. While the Regent Diamond was the centrepiece of the King
Louis XV crown, and worn by him at his coronation in February 1723,
Marie Antoinette, wife of
Louis XVI, wore it in a black velvet hat. The Royal
French Blue was transformed into the
Hope Diamond now in the
Smithsonian Institution in Washington, D.C.. With two remaining jewels of the
Renaissance, the
Côte-de-Bretagne red spinel and the
Dragon perle, a pin shaped into the form of a dolphin, the crown jewels collection contains as well among others, the emerald set and pearl earrings of
Empress Josephine, the micromosaic and the emerald and diamond sets of
Empress Marie Louise, the pair of
bracelets of rubies and the emerald diadem of the
Duchess of Angoulême, the sapphire set of
Queen Marie Amélie, a diamond cross of the
Order of the Holy Spirit and a diamond portrait box of
Louis XIV. ==Gemstones in the Natural History Museum and École des Mines==
