Researchers Consolidate Conflicting Provenance Claims of Queen Marie-Amélie’s Mellerio Pearls

M.S. Rau of New Orleans is offering a pair of natural pearl and diamond earrings presented as Queen Marie-Amélie’s Mellerio pearls, accompanied by a Swiss Gemmological Institute SSEF certificate, a family tree, a letter from Jean d’Orleans and a painting cited in the SSEF report. Bill Rau, third generation owner of M.S. Rau, described them as, "These extraordinary natural pearl and diamond earrings, worn by Queen Amélie, the last Queen of France, are among the most important works we have ever been able to present."

Technically the lot is described as two matched natural saltwater drop pearls set in diamond frames attributed to Mellerio dits Meller. Precise measurements published in dealer and blog material list Earring 1 pearl at 10.95 x 11.05 x 14.80 mm and Earring 2 pearl at 10.85 x 10.90 x 14.90 mm. Sale documentation is said to include photographs of Princess Isabella wearing the earrings and the letter from Jean d’Orleans asserting descent through his grandmother Princess Isabella.

Dating and maker attribution diverge in the public record. Multiple accounts state the pearls date to circa 1790 while a line within the same Royalwatcherblog text reads "Dating from around 1890." Royalwatcher and other social posts also note that the diamond frames were later enhanced by Mellerio in the later nineteenth century, a detail that could account for two different date references but remains unresolved in the available packet.

Provenance claims are consistent around a Bourbon-Orléans descent and mid-20th century public wear. Royalwatcherblog lists multiple occasions where the Countess of Paris wore the pair, including the weddings of Prince Henri, Count of Clermont and Duchess Marie-Thérèse of Württemberg in 1957, Duke Carl of Württemberg and Princess Diane of Orléans in 1960, two 1964 weddings for Princess Isabelle of Orléans and Prince Amedeo Duke of Aosta, Prince Michael of Greece in 1965, and Prince Jacques Duke of Orléans in 1969. Robb Report notes the earrings "descended directly through the Bourbon-Orléans line and come with a family tree that provides more context."

Price reporting varies between $7.95 million and $8 million for the asking price. Robb Report invoked the 2018 Sotheby’s sale of Marie Antoinette’s pearl and diamond pendant for $36 million to provide market context, observing that a sub-$8 million price point appears comparatively modest.

Public social feeds that ran alongside the dealer listing introduce further confusion. Instagram and Facebook posts in the same feeds quote an inventory entry referring to a Duchesse de Chartres gift from Queen Elena of Italy and an Art Deco pair with baroque pearls of approximately 100 grains each. Those Art Deco and 100 grain descriptions do not match the measured matched drops identified by SSEF and M.S. Rau, suggesting two distinct sets of jewels have been conflated in social media copy.

The most concrete anchors in the dossier are the SSEF certificate, the painting referenced in that certificate, and the Jean d’Orleans letter and photographs included in the sale packet. Clarifying whether the circa 1790 date applies to the pearls themselves and whether Mellerio’s work dates to the later nineteenth century depends on inspection of the SSEF full report, the Mellerio archive record for the remounting and the Jean d’Orleans letter that traces Bourbon-Orléans ownership. The outcome will determine whether these matched natural saltwater drops are indeed among the handful of Queen Amélie jewels known to survive.
