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.
The silver and 18-karat gold JAR “Moghul” pendant brooch pictured above sold for $432,500, going for well above its pre-sale estimate high of $300,000.
The piece was created in 1999 and designed as a stylized bombé architectural turret. It’s 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.
It has a detachable chain set with single-cut diamond stations and comes in a JAR pink leather case.
There also was a JAR “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 sold within its pre-sale estimate range when it garnered $2.8 million Tuesday.
JAR’s two jewels were sold 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.
Below are a few pieces that joined the JAR thread ring as top lots of the Christie’s New York sale, including the 8-carat pink diamond that came in at No. 2.
