GENEVA – On 15 May 2019, Geneva Magnificent Jewels auction will be highlighted by superb jewels of exceptional craftsmanship, historical provenance and pieces by the most sought-after jewellery houses including Cartier, Bulgari, Van Cleef & Arpels and Harry Winston. The jewels will be on view at Christie’s London from 9 to 11 April and at the Four Seasons Hotel des Bergues, Geneva from 10 to 15 May during Christie’s Luxury Sales.

HISTORICAL JEWELS

An early 19th century emerald and diamond fringe necklace with royal provenance will be offered (estimate: CHF/USD 1,500,000 – 2,500,000,). Owned by Henri d'Orléans, Duke of Aumale (1822-1897), the jewel was gifted to his goddaughter Princess Hélène of France, Duchess of Aosta (1871-1951) on her marriage on 25 June 1895 to the Prince Emanuele Filiberto of Italy (1869-1931), Duke of Aosta. During the 20th century, the necklace became part of the equally prestigious collection of Sybil Sassoon, Marchioness of Cholmondeley (1894-1989), the daughter of Sir Edward Sassoon and Baroness Aline de Rothschild. Miss Sassoon's collection comprised jewels of exceptional quality. Part of her jewellery was sold at Christie's and this historic necklace consequently became part of an important private collection.

A rare aquamarine and diamond tiara by Fabergé (estimate: CHF/USD 230,000-340,000) will be offered at auction for the first time. Made in 1904 as a wedding gift from Frederick Francis IV, Grand Duke of Mecklenburg-Schwerin (1882-1945) to his bride Princess Alexandra of Hanover and Cumberland (1882-1963), this Fabergé tiara is of symbolic design with forget-me-not flowers tied with ribbon bows, signifying true and eternal love, pierced by arrows representing cupid, a token of endearment, attraction and affection.

A leading jewel of the auction will be The Jonker V, a beautiful rectangular-cut, D colour diamond ring weighing 25.27 carats, set by Harry Winston (estimate: CHF/USD 2,500,000 – 3,500,000). On 17 January 1934, the extraordinary 726 carats rough diamond, from which the Jonker V was cut, was named after Johannes Jacobus Jonker, who discovered it. At the time the Jonker was the fourth largest gem quality diamond ever unearthed. The stone was subsequently purchased by Joseph Bastiaenen of the Diamond Corporation Ltd., a company owned by Sir Ernest Oppenheimer. In 1935, it became the first of Harry Winston’s renowned acquisitions of exceptional and important diamonds. The Jonker was displayed during the Silver Jubilee Celebrations of the Coronation of King George V and Queen Mary that took place the same year.
