An American Art Nouveau 18 karat gold stick pin with enameling and black opal by Marcus & Co. The stick pin has a cabochon opal surrounded with four enamel side sections decorated with gold relief arabesque designs. The multi-generational New York firm of Marcus & Co was founded by an ambitious young German immigrant who had trained at a prominent Dresden court jeweler. In 1892, after working with Charles Lewis Tiffany, Hermann Marcus and his sons William and George together set up a business that soon became a glittering New York society institution renowned not only for its superb diamonds, colored stones and pearls, but also its instantly recognizable, original design style. The firm produced great jewels in the Art Nouveau and Arts & Crafts sensibility, with George, the artist/designer, drawing inspiration from sources as diverse and exotic as the contemporary French masters, the Moghuls and Maharajahs, the garland style of the Ancien Regime, and the genius of Renaissance goldsmiths. George''s distinctive, confident hand was always discernible in Marcus creations. Working as a team with George, his brother William was a gem and pearl connoisseur who travelled the world hunting fine gem material, including purchasing the entire production of never-before-seen black opal in Lightning Ridge Australia in 1908. Marcus exhibited at the 1900 Exposition Universelle in Paris, and
their work won prizes at the prestigious Society of Arts & Crafts of Boston. The firm and family were well-known for their charitable activities and promotion of young jewelers such as Raymond Yard.
