JAR - High Jewels

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.

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.

Mauboussin

Mauboussin was founded in 1827 by M. Rocher and J. Noury. They specialized in the manufacture of unique and exquisite jewellery. By the early 1930s they had successfully exhibited their pieces dedicated to gemstones. One exhibition centered around emeralds, another for rubies while the third was dedicated to diamonds. Those exhibitions cemented Mauboussin's reputation as one of the world's most exquisite jewelers.

Today Mauboussin is regarded as the French equivalent to Tiffany's and is a global jewellery brand.
