RAPAPORT... A storied diamond connected to the Oppenheimer family will be among the top lots at next month’s
Geneva auction at Christie’s, with a presale estimate of $2.5 million to $3.5
million.
The rectangular-cut, 25.27-carat, D-color Jonker V ring will go under
the hammer at the Magnificent Jewels sale on May 15, the auction house said
last week.
The stone was cut from a 726-carat rough South African
farmer Johannes Jacobus Jonker discovered in 1934. At the time, the Jonker was
the fourth-largest gem-quality diamond ever unearthed.
A subsidiary belonging
to Sir Ernest Oppenheimer, the founder of Anglo American and a former De Beers chairman, bought the polished stone. In 1935, Harry Winston
purchased the diamond and set it in a ring. Later that year, it was displayed
during the Silver Jubilee celebrations for King George V and
Queen Mary.
Christie’s will also offer a heart-shaped, fancy-deep-blue diamond
ring, featuring two stones weighing 2.22 carats and 2 carats, valued at $3.5
million to $4.5 million. Separately, an old cushion-cut, 118.05-carat, fancy-yellow diamond
carries an estimate of $2.5 million to $3.5 million.
Other notable lots are a necklace comprising 110 natural pearls
with a presale estimate of $2.5 million to $3.5 million, and a pear-shaped,
75.61-carat emerald pendant necklace expected to fetch $2 million to $3
million.
In addition, the Geneva sale will feature an early-19th-century
emerald and diamond fringe necklace Henri d’Orléans, duke of Aumale, gave to
his goddaughter, Princess Hélène of France, for her 1895 wedding to Prince
Emanuele Filiberto of Italy.
The auction will also include jewels from Cartier,
Bulgari, Van Cleef & Arpels and Harry Winston.
Christie’s will preview the jewels in London from
April 9 to 11, and in Geneva from May 10 to 15.
