Continuing the recent streak of truly exceptional diamonds being offered at auction is a stone dubbed ‘The Orange’, which at 14.82 carats is the largest orange diamond ever graded by the GIA, and so may be the largest in existance. The pear-shaped gem, which is fancy vivid orange with VS1 clarity, is more than double the size of the previous record holder (which was under 6 carats) and carries an estimate of $18 million to $21 million. It will be the last lot of the day.
18 pieces of jewelry from the enviable collection of Parisian society grand dame Hélène Rochas (1927-2011), wife of the famed fashion designer Marcel Rochas, will be offered at the sale as lots 218 thru 235. These include a number of pieces by René Boivin, as well as signed Cartier, Van Cleef & Arpels and Verdura jewels.
Bolivian mining tycoon Simón Itturi Patiño (1862-1947), ‘The Tin King’, was famously a collector of exceptional gemstones and three of those pieces will be offered for sale. The highlight of his collection was a necklace bought for his wife in 1938 that featured a 45-carat emerald cross purchased by Cartier from Queen Eugenia Victoria of Spain in 1937. Dubbed ‘The Andean Cross’ it had previously belonged to Queen Isabel II of Spain and Empress Eugenie of France, and Cartier matched another 100 carats of emerald to create the necklace. Sadly the cross is no longer there and the original necklace was shortened to create a matching pair of earrings, which are also being offered (Lot 214 and Lot 215). The third piece is a 32.65-carat cushion-shaped white diamond ring by Chaumet (Lot 213).
More exceptional emeralds are being offered that were once owned by HRH Princess Faiza of Egypt (1923-1994). One is an emerald drop necklace by Van Cleef & Arpels (and is featured on the cover of the auction catalog) and the other is a Cartier sautoir-style beauty (Lot 209 and Lot 254).
And finally, a last emerald piece to whet your appetite.
The sale will be held in two sessions at the Four Seasons Hotel des Bergues in Geneva, the first at 2:00pm (Lots 1-163) and then 7:00pm (Lots 164-286).
