Romanov sapphire sells for over 4.1 million Swiss francs in Geneva

The Geneva sale

Sotheby's sold a 197.80-carat Ceylon sapphire, set in a diamond-studded bracelet, at its Geneva auction late on Wednesday, 11 November 2026. The stone fetched more than 4.1 million Swiss francs, which the auction house put at about $4.9 million. Its estimate had been between 850,000 and 1.7 million francs, so the final price was more than twice the top of that range. The buyer was a private collector who was not identified. The cushion-shaped stone was billed by the auction house as a very rare gem.

Before the sale, Andres White Correal, Sotheby's chair of jewellery Europe and Middle East, described the season's offering in these words:

“The extraordinary success of our Royal & Noble Jewels sales reflects collectors' enduring fascination with jewels that combine exceptional gemstones, craftsmanship and history.”

From the Romanov court to Geneva

The dowager empress Maria Feodorovna, mother of Nicholas II, wore the sapphire at the Winter Palace Ball of 1903, which the auction house described as the last great spectacle of Imperial Russia. Sotheby's says the stone entered the Romanov jewels in the 19th century and was recorded in an inventory after the 1917 revolution. The Soviet government later sold it, along with other imperial treasures, to raise hard currency. Ganna Walska, an American opera singer of Polish origin, bought it in 1927, and it resurfaced at auction in 1971 and in Geneva in 1992. Cartier created the diamond bracelet that now holds it in 2015. The Fersman catalogue, compiled between 1924 and 1926, presents it as a brooch mounted by Fabergé in a diamond setting, according to Sotheby's.

Royal and noble lots in the same sale

Sotheby's said the royal and noble jewels offered at the Geneva sale reached a combined total of 15.3 million francs. Correal said the season was led by rare pieces tied to some of Europe's imperial and royal families, from the Romanovs to the Houses of Orleans and Braganza. A Cartier opal and diamond tiara, produced in the 1930s for Mary Cavendish, Duchess of Devonshire, reached 1.66 million francs, and its low estimate had been 780,000. A Mellerio dits Meller diamond tiara-necklace, a wedding present to Princess Marie Isabelle d'Orléans in 1864, made 512,000 francs, with its low estimate at 300,000. The Geneva sale brought together jewels once owned by prominent European noble families.

Royal provenance and auction prices

Research by ALT/FNDATA, a provider of collectible assets data, analysed more than 165,000 jewellery lots sold by Sotheby's, Christie's and Bonhams over the past decade. Pieces with named royal or noble provenance reached a median of 2.3 times their presale estimates, against 1.9 times for pieces linked to other public figures. Romanov-linked jewellery posted the highest multiple, at 3.1 times the low estimate, ahead of British royalty at 2.9 and French royalty at 2.6. Sharon Obuobi, the founder of ALT/FNDATA, said the findings show the appeal of royal ownership:

“A crown pushes a price higher than any famous name”

Sotheby's has classed noble-linked jewellery as its own category since 2007. In 2018 a pearl pendant owned by Marie Antoinette went for 43.1 million Swiss francs at Sotheby's Geneva, where presale guidance had been 1.6 to 2.9 million francs.
