The Marie Antoinette Pendant Sale, November 2018
The Marie Antoinette Pendant Sale, November 2018
Sotheby's Geneva, the Bourbon-Parma jewels, and a CHF 53 million reaffirmation of royal provenance
The Marie Antoinette pendant sale of November 2018 is the shorthand reference to Royal Jewels from the Bourbon-Parma Family, an evening sale held by Sotheby's Geneva on 14 November 2018. The auction offered approximately 100 lots descended through the Bourbon-Parma family, including 10 lots with documented provenance to Queen Marie Antoinette of France. The headline lot — a natural pearl and diamond pendant — sold for CHF 36.16 million, a record for a pearl at auction. The aggregate sale total exceeded CHF 53 million.
The Bourbon-Parma material
The jewels offered were drawn from a single private family collection that had passed continuously from Marie Antoinette and her daughter Marie-Thérèse Charlotte through subsequent Habsburg, Bourbon, and Bourbon-Parma generations into the 21st century. The material spanned roughly 250 years of European royal collecting and included pieces from the courts of France, Naples, Parma, Tuscany, Spain, and Austria. Roughly ten of the lots were specifically documented as having belonged to Marie Antoinette herself; others were associated with subsequent royal owners, and many had been remounted in the 19th century into settings that reflected the taste of those later owners.
The pearl pendant
The headline lot, Lot 100, was the natural drop pearl of approximately 26 mm, mounted as a pendant with a diamond cap and bow in a 19th-century setting. The pearl itself was documented as having been part of Marie Antoinette's personal jewellery and as having descended through the family from her daughter onward. Pre-sale estimate was CHF 1–2 million; bidding extended through 16 increments to a hammer of CHF 32 million, with the premium taking the total to CHF 36.16 million. The buyer was an Asian private collector and has not been publicly identified. The result remains the world record for a pearl at auction.
Other Marie Antoinette lots
Several other lots with Marie Antoinette provenance also exceeded estimate substantially. A pair of natural pearl and diamond ear pendants sold for CHF 2.16 million against an estimate of CHF 200,000–300,000; a diamond brooch attributed to Marie Antoinette realised CHF 2.04 million; a diamond ring with Bourbon provenance reached CHF 451,500. Across the Marie Antoinette lots, average premium over high estimate was on the order of 5x to 10x.
Wider results
Beyond the Marie Antoinette material, the sale included important pieces with provenance to Empress Marie Louise (second wife of Napoleon I), Queen Maria Pia of Portugal, and the Duchess of Parma. A turquoise and diamond tiara from this group realised CHF 1.5 million; a pearl and diamond rivière sold for CHF 1.7 million. The total of CHF 53.2 million for the sale exceeded the high pre-sale estimate of CHF 8.4 million by more than 6x.
Why the sale mattered
The 2018 Bourbon-Parma sale was the most consequential royal-jewel auction since the 1987 Sotheby's sale of the Duchess of Windsor's collection. Three factors were unusual in combination. The first was the depth of family documentation: most of the lots were supported by inventory entries, photographs, or correspondence that placed them in named royal hands across multiple generations. The second was the natural-pearl content: the family had retained natural pearls from the 18th century forward, at a time when the wider trade had moved almost entirely to cultured material. The third was the timing: the sale came in a market period in which the upper-end colored-stone and provenance segments were strong and Asian private buyers were active. The combination produced a result that reset price expectations for documented royal provenance.
Market afterlife
In the years following 2018, royal-provenance jewellery has continued to perform at premium when documentation is solid. The Sotheby's Royal Jewels: A Princely Collection sale (2019) and the Christie's Magnificent Jewels evening sales of subsequent years have included royal-provenance lots that traded at multiples of comparable non-provenanced material. The Bourbon-Parma sale established that the premium can be very large when the genealogical chain is unbroken.
In the trade
For dealers and collectors, the relevant references are the Sotheby's catalogue and post-sale reports, which contain the descent documentation for each lot. The catalogue itself has become a standard reference for late-18th-century and 19th-century European royal jewellery and is frequently cited in subsequent auction notes for related material.
