 Joel A. Rosenthal | His name might not be as recognizable as Cartier or Van Cleef & Arpels, but Paris-based, American jeweler Joel A. Rosenthal is considered one of the world's most influential gem artists. Rosenthal is famously reclusive and does not lend his designs for magazine shoots or red carpet appearances, however his jewelry is some of the world's most sought after. |  JAR Poppy Brooch |
 | Raised in the Bronx, New York, the 73-year-old designer is highly regarded for his pavé work– a technique that entails setting diminutive gems in even smaller settings to create a rolling surface of stones. Considered one of the greatest contemporary jewellers, JAR is synonymous of exceptional craftsmanship. JAR jewels are rare and when they come up for auction they attract the interest of the world’s most demanding collectors. |  |
