118ct. Yellow Smashes Estimate at Christie’s

Chrisites Geneva The Siba Diamond

A diamond bought in memory of late diamantaire Sam Abram sold for more than double its high estimate at Christie’s Geneva auction Wednesday.

The cushion brilliant-cut, 118.05-carat, fancy-yellow, VS2-clarity stone fetched $7.1 million, or $60,000 per carat, at the Magnificent Jewels auction. The diamond, which was estimated at $2.5 million to $3.5 million, was purchased by Siba Corp. in honor of its former president. The company subsequently named it The Siba Diamond.

Three ruby pieces broke the top 10, all selling for well above their estimates. A 22.86-carat Burmese ruby ring by Harry Winston went for $7.2 million against its high estimate of $3 million, a final price of $314,900 per carat. Meanwhile, a Van Cleef & Arpels ruby and diamond necklace, which was valued at $400,000 to $600,000, garnered $2.4 million, and a ruby and diamond bracelet by the same jeweler fetched $1.6 million. That piece was estimated at $150,000 to $250,000.

A necklace comprising 110 natural pearls achieved $5.8 million, well above its high estimate of $3.5 million. All other pearl pieces of note offered at the sale also exceeded their original estimates, Christie’s said.

Other notable lots included a pear-shaped, 75.61-carat emerald pendant necklace that belonged to the Grand Duchess Vladimir of Russia, which sold for $4.3 million, or $57,300 per carat. It was estimated at $2.3 million to $3.5 million.

“Natural pearls and jewels with noble provenance, such as the 75.61-carat emerald from Grand Duchess Vladimir of Russia, found much acclaim and sold for far above their presale estimates,” said Rahul Kadakia, Christie’s international head of jewelry. “Also of note was the 118-carat, fancy-yellow diamond that was purchased by Siba Corp. in honor of Sam Abram, a prominent figure in the jewelry world, who very sadly passed away last week.”

In addition, the rectangular-cut, 25.27-carat, D-color Jonker V diamond connected to Anglo American founder and former De Beers chairman Sir Ernest Oppenheimer fetched $3 million against a valuation of $2.5 million to $3.5 million.

Christie’s sold 87% of all lots on offer, it said. The sale brought in a combined $62.1 million.

Rare 25ct. Diamond to Lead Christie’s Geneva

Jonker Diamond

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.
