Background
Every autumn, Geneva hosts the major jewellery and watch sales of the international auction houses. Christie's was offering the “Bulgari Pink”, a 24-carat pink diamond set in a platinum ring. According to Christie's, the jewel had belonged to a European aristocratic family for around 70 years. An ancestor of the previous owner had bought the rough stone in India and then had it cut by the jeweller Bulgari.
The key points
The “Bulgari Pink” sold for 12.1 million francs on Tuesday 10 November 2026 at a Christie's auction in Geneva, according to the Keystone-ATS news agency. The price remains below the high estimate, set at 15 million francs. The buyer's identity was not disclosed, in line with the auction house's practice.
Max Fawcett, head of Christie's jewellery department, explained that above ten million francs the circle of collectors is small. He added that all parties were satisfied with the result. According to him, the ring will be given as a gift and worn.
The stone is graded “fancy intense pink” and type IIa, a mark of very high chemical purity. According to Christie's, only 2 % of diamonds belong to this category.
Key figures
- 12.1 million francs : hammer price of the “Bulgari Pink”
- 15 million francs : high estimate before the sale
- 24 carats : weight of the diamond
- 70 years : period of ownership by the same family, according to Christie's
Analysis
- According to Max Fawcett (Christie's): above ten million francs, the circle of collectors is small; a price below the high estimate therefore satisfies all parties.
