Signed JAR ring with 10+crt yellow sapphire

This is something you wouldn't see much. A JAR jewel being offered in public. Normally owners of JAR jewelry cherish their jewel and hand it over to their offspring. And JAR himself, being extremely picky to who he would sell his pieces, also doesn't make it easier for the public to be able to obtain his pieces.

But here we have one of JAR’s earliest pieces, a wide yellow sapphire band ring in yellow gold made around 1980, echoing Bulgari’s design aesthetic from that period; where JAR use to work before he opened his own high jewellery boutique at the famous Place Vendôme in Paris.

This ring belonged to Mrs. B, heir to a famous Rotterdam industrial who was initiator of a famous Dutch museum.

Extra information: JAR - JAR short for Joel Arthur Rosenthal - was born in the Bronx, New York in 1943 under the name of Joel Arthur Rosenthal. The famous Paris-based jewellery designer JAR has been called “the Fabergé of our time” by designer Diane von Furstenberg. Or as David Bennett, chairman of Sotheby’s Geneva, puts it, "trust the hype, in terms of creativity, JAR is without peers.” These insights from people who know what they are talking about helps explaining the beyond-normal prices that JAR pieces have brought at auctions in recent years.

After graduating from Harvard and after a short stay at Bulgari as salesman he spent most of his life in the French capital. In 1978 he opened his his own high jewellery boutique at the famous Place Vendome. A boutique without display window nor opened at regular hours. With craftsmen in France and Switzerland, JAR produces less than 100 jewels a year. Each is one-of-a-kind and excecuted with Rosenthal's meticulous attention to detail using the finest-quality gems. And being a true diva, he reserves the right to refuse to sell an item if he doesn't think it would look good on the intended wearer.
