The phrase JAR Joel Rosenthal Vendôme names the convergence of designer, address and house that constitutes one of the most singular operations in twentieth and twenty-first century fine jewellery. Joel Arthur Rosenthal opened the JAR boutique at 7 Place Vendôme in Paris in 1977 and has worked from that address continuously since, producing a small annual output of jewellery to commission and for the boutique's tightly controlled retail.

The Founder

Joel Arthur Rosenthal was born in the Bronx in 1943 to schoolteacher parents, attended the Bronx High School of Science and took an undergraduate degree at Harvard in art history and philosophy, graduating in the mid-1960s. He moved to Paris before the end of the decade with his partner Pierre Jeannet, and the pair tried several modest commercial ventures before turning to jewellery design. Rosenthal sold sketches and finished pieces to other Place Vendôme houses for several years, and in 1977 the two founded JAR at 7 Place Vendôme. The boutique has remained at that address.

The Place Vendôme Address

Number 7 Place Vendôme is among the most prestigious commercial addresses in Paris. The square itself was designed by Jules Hardouin-Mansart for Louis XIV and has been the centre of French fine jewellery since the nineteenth century, with neighbours including Boucheron at number 26, Chaumet at number 12 and Van Cleef & Arpels at number 22. JAR's choice of the address signalled membership of the haute joaillerie tradition while the maison's day-to-day operation, with a closed boutique window showing typically a single flower in a vase and clients seen only by appointment, set it apart from the more public retail of its neighbours.

The House

Rosenthal designs every piece personally and works with a small team of bench jewellers, stone-setters and lapidaries assembled around the atelier on the upper floors of the Vendôme building. The annual production is small and unpublicised. The maison does not advertise, does not publish a catalogue, and grants very few interviews. Public knowledge of JAR's work derives primarily from auction catalogues, the writings of a small group of gem journalists, and the two institutional exhibitions, the smaller display at Somerset House in London in 2002 and the major retrospective Jewels by JAR at the Metropolitan Museum of Art in New York in 2013.

Pierre Jeannet

Pierre Jeannet, Rosenthal's partner of more than fifty years, is the second principal of the maison and is widely understood within the trade as central to its commercial direction and client management. Jeannet's role has been deliberately backstage, but the partnership of designer and director is structurally important to JAR's manner of operating.

Reputation and Discretion

The JAR name has become a metonym in the international trade for designer-led haute joaillerie operating outside the conglomerate-owned Vendôme model. Rosenthal's refusal to expand, to franchise, to license or to open additional boutiques is taken as an emblematic stance, and the maison's chosen reticence has been a more effective marketing strategy than any conventional one would have been.
