Joel Arthur Rosenthal, born in New York City, was graduated in Art History and Philosophy from Harvard in 1965 before moving to Paris where he opened a shop in the Place Vendôme in 1978, his initials, JAR, being the only source of identification on the trade. Mr. Rosenthal works with his partner Pierre Jeannet, to create exquisite jewels, superbly crafted in unique settings, revealing a personal vision, often interpreting Nature’s beauty. His work is imaginative and meticulous, incorporating stones in unexpected colour combinations. Only 70 to 80 jewels are created each year, for an equally rare clientèle. In November 1987, in celebration of his 10th anniversary in Paris, Mr. Rosenthal held an exhibition of his work at the National Academy of Design in New York City. In November 2002, a retrospective of 400 jewels was held at the Gilbert Collection, Somerset House, in London.
Lastly, a 4-month major exhibition opened at the Metropolitan Museum of Art in New York in November 2013, making of Joel Rosenthal the only living jewellery designer to have a dedicated retrospective in this museum.
