An Art Nouveau brooch with pearls, diamonds and emerald by Marcus & Co.

Gemological Institute of America certificate #2171449596 states the pearls are natural saltwater button pearls. 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-se
en 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. Plique-a-jour enamel was an art in which Marcus & Co. excelled, creating jewels with unprecedented three-dimensional depth in this medium. The firm and family were well-known for their charitable activities and promotion of young jewelers such as Raymond Yard.

A Tiffany Studios New York "Dragonfly" glass and bronze chandelier. This elegant chandelier is composed of a choice selection of glass, which makes this an exceptional example of Tiffany''s iconic dragonfly lamp. The dragonflies are composed of dark green glass bodies, variegated blue glass wings and red glass eyes. The cabochon glass jewels that surround this chandelier depict emeralds, sapphires and topaz. The two top and three bottom borders are made up of various colors of rippled glass. This exciting glass composition rests upon a ground of green, green/blue and brown glass. While Tiffany was largely credited for his company''s glass innovations during his lifetime, recent archival research has shed light on the unsung heroes behind his genius. Two such figures were responsible for the astounding effects of this dragonfly lamp: Tiffany had gone through four chemists before he landed on Arthur J Nash, a chemist previously employed at the White House Glass Works in Stourbridge. England. It was Nash''s formulas, developed from before his employment at Tiffany, that became the core of Tiffany''s palette. Nash was no stranger to experimentation, adding unconventional materials such as birch bark and burnt oats to create his amber glass. Clara Driscoll, head of the Tiffany Studios Women''s Glass Cutting Department, designed the dragonfly lamp, earning much acclaim for h
er artistic prowess in her time. (For more information on her work see "A New Light on Tiffany: Clara Driscoll and the Tiffany Girls," by Martine Eidelberg, Nina Gray, and Margaret K. Hofer, 2007.) Louis Comfort Tiffany''s "Dragonfly" lamps have become so iconic and loved because the artisans who made them were not limited in color as they were when making floral and geometric shades. We can imagine that the dragonflies that adorn the lower edge of the shade are flying low across a verdant field. Similar chandeliers are pictured in: "Tiffany Lamps and Metalware: An illustrated reference to over 2000 models," by Alastair Duncan, Woodbridge: Suffolk: Antique Collectors'' Club, 1988, p. 230, plate 891-893.
