A fancy-deep-blue diamond ring with a high estimate of CHF 14 million ($14.1 million) will go under the hammer at Christie’s Geneva Magnificent Jewels auction next month.
The 7.03-carat stone, mounted by Moussaieff, will lead the November auction, Christie’s said Thursday. Another prominent lot is a 46.93-carat, D-color, internally flawless diamond ring, which is expected to fetch CHF 3.8 million to 4.5 million ($3.8 million to $4.5 million).
Christie’s will also offer a 42.97-carat Burmese sapphire pendant, valued at up to CHF 3 million ($3 million), and a pair of untreated Colombian emerald earrings, each weighing over 7.5 carats, with a presale estimate of CHF 1 million to 1.5 million ($1 million to $1.5 million).
Other items on offer include a rare Belle Époque brooch, dated circa 1910, which was procured by the Australian opera singer Dame Nellie Melba at the height of her career. The turquoise and diamond piece is valued at CHF 250,000 to CHF 350,000 ($252,046 to $352,864).
The sale also encompasses several Art Deco pieces from Cartier. Three brooches, formerly in the collection of Countess Béatrice of Granard OBE, have a high presale estimate of CHF 220,000 ($221,856). A diamond Cartier bandeau, which can also be worn as a choker, two bracelets and a brooch, is valued at up to CHF 500,000 ($504,193).
Highlights from the collection are available for viewing at Christie’s London on October 22 and 23, and at the Four Seasons Hotel des Bergues, Geneva, from November 7 to 12.
