La Païva

The Donnersmarck Diamonds were part of the collection of La Païva, Countess Henckel von Donnersmarck (1819 – 1884), arguably the most famous of 19th – century French courtesans, whose vertiginous trajectory from modest circumstances in her native Russia to the highest circles of European aristocracy was sensational.


In 1855, she purchased a building plot on the Champs Elysées. L’Hôtel de La Païva was to be one of the most lavish mansions ever built on the famous avenue, and became renowned for its fabulous social and intellectual gatherings. Also in the 1850s, La Païva met one of Europe’s richest men, the handsome and charismatic 22 – year – old Prussian industrialist and mining magnate Count Guido Henckel von Donnersmarck (1830 – 1916).




He was immediately captivated by La Païva’s seductive charms, extraordinary mind and business acumen. Their relationship was the talk of Paris high society and in 1871, the two were married. Following La Païva’s death in 1884, the Count, who was created prince in 1901, remarried, taking as his second wife Katharina Wassilievna de Slepzoff (1862 -1929) a beautiful and refined Russian aristocrat. The diamonds remained in the Donnersmarck family for more than a century until they appeared at auction at Sotheby’s in 2007. They come to auction this November after having been in a private collection for the last 10 years (Estimate US$ 9 – 14 million / CHF 18.8 – 13.7 million).

Treasured by the same European noble family for over 45 years, it was mounted as a ring by the ‘king of diamonds’, Harry Winston.
