Christie's to Offer 100-Carat Diamond Necklace at Auction 8 November

A pedigreed, 100-carat diamond necklace and three Bulgari snake bracelet watches will join the largest pear-shaped pink diamond to highlight Christie’s upcoming jewelry sale in Geneva, the auction house announced Thursday.

Last month, Christie’s unveiled The Fortune Pink, an 18.18-carat fancy vivid pink diamond as the top lot of the sale, with a presale estimate between CHF25 million (US$25 million) and CHF35 million.

The 250-lot sale will take place on Nov. 8 at the Four Seasons Hotel des Bergues in Geneva.

The Rivière diamond necklace was offered for sale from the collection of the Lord and Lady Weinstock. It features a pear-shaped diamond of 10.33 carats and is expected to sell for between US$550,000 and US$750,000.

Arnold Weinstock was an English industrialist and businessman, known for making General Electric Company (GEC) one of Britain's largest and most profitable companies in the 1960s-90s. He died in 2002 at the age of 77.

Lady Weinstock, born Netta Sobell, died in 2019. Her family owned Radio & Allied Industries Ltd., which merged with GEC in 1963 and became the largest shareholder of the conglomerate.

Their collection of Old Master paintings, English and European furniture, and other items, totalling roughly 300 pieces, will be sold across three live auctions at Christie’s London later this year, the auction house announced earlier this week.

Additionally, three iconic Bulgari “Serpenti” bracelet watches from the 1960s will be offered at Christie’s sale of magnificent jewelry on Nov. 8, with a low estimate of around US$200,000 each. The snake bracelets were made popular by famous actors in the 1960s, most notably Elizabeth Taylor, who wore a gold, diamond, and emerald “Serpenti” bracelet watch during the filming of Cleopatra in 1962.

Further highlights of the 250-lot auction include a 101-carat diamond, which is expected to fetch up to US$3.5 million; an emerald-cut diamond ring by Graff, with a presale estimate of between US$3 million and US$5 million; and a 14.84-carat Kashmir sapphire ring by Cartier, with a low estimate of US$1 million.

All lots will be on public exhibition from Nov. 3-8 at the Four Seasons Hotel des Bergues in Geneva.
