New York--An 8.42-carat pink diamond ring is expected to lead Christie’s New York jewelry sale next month.

The cut-cornered rectangular modified brilliant-cut fancy intense pink diamond is VVS1 clarity and potentially internally flawless. It is flanked on either side by a tapered baguette-cut diamonds and mounted in platinum and rose gold.

 It is estimated to sell for $4 million to $6 million.

Scheduled for April 17, the Magnificent Jewels auction has more than 200 lots, with estimates ranging from $4,000 to $4 million.

Beyond the pink diamond, highlights include two notable pieces by JAR, whose meticulously crafted jewels are renowned worldwide.

Born in New York City in 1943, Joel Arthur Rosenthal graduated from Harvard in 1966 before moving to Paris. He worked as a screenwriter and needle stitcher, as well as with Bulgari in New York, before moving back to Paris and opening a store on the Place Vendôme with his partner, Pierre Jeannet, for his jewelry creations.

His pieces are being sold in the Christie’s auction to benefit the Art for Justice Fund, which connects criminal justice advocates with artists to help reform the criminal justice system in the United States.

20180329 JAR brooch

The first JAR piece is the “Moghul” pendant brooch pictured above, created in 1999 and set in silver and 18-karat gold.

The brooch was designed as a stylized bombé architectural turret and is pavé-set with circular-cut amethysts surrounding a 14.77-carat cushion-cut sapphire and a border of single-cut diamonds. It also has a single-cut diamond cap suspending a natural pearl tassel and the reverse side is set with pavé diamonds.

The piece has a detachable chain set with single-cut diamond stations and comes in a JAR pink leather case.

The brooch is estimated to sell for between $200,000 and $300,000.

20180329 JAR ring

The second JAR piece is a “thread” ring (pictured above), so named for the perceived lightness of the setting and fine pavé work.

It features an elongated oval brilliant-cut diamond weighing 22.76 carats and of D color and VVS1 clarity, and a diamond-set two-tiered threadwork gallery and hoop mounted in platinum. It also includes a JAR case.

The ring is expected to sell for $2.5 million to $3.5 million.

It was the highlight of the 2006 Magnificent Jewels auction at Christie’s New York, where it was offered as part of the collection of actress and film producer Ellen Barkin. At the time, it sold for $1.8 million, well over its pre-sale estimate of $1.2 million.

Other highlights of the upcoming sale include a selection of colored diamonds, white diamonds and gemstones, along with signed period and modern jewels from houses like Boucheron, Bulgari, Cartier, David Webb, Harry Winston, Tiffany & Co. and Van Cleef & Arpels.

Christie’s said the auction also includes five important blue diamond rings from “esteemed” private collections.
