The Plumb Club recently welcomed two firms into its membership, LeVian Corporation and Wolf Designs. The LeVian family have been purveyors of fine jewelry in Persia since the 15th century. In 1950 the American division of the company was founded and is based in New York City.

Wolf Designs, based in Malibu, Calif., began in Germany in 1834 with leather-covered jewelry boxes before expanding throughout Europe. Today, Wolf Designs manufactures jewelry boxes, home accessories, and fine gifts.
