Marcus & Co.
Throughout the early 20th century, Marcus & Co. established a reputation as one of the finest American producers of Art Nouveau jewelry. The firm’s innovative techniques included the use of plique-à-jour enameling. During the 1900s, this rare method was used by only three other jewelry companies in the United States — Tiffany & Co., Riker Bros. and Whiteside and Blank.
Marcus & Co. was founded in 1892, in New York City, by Herman Marcus and his son William. Herman was born and raised in Germany, where he worked as a jeweler for Ellemeyer, the court jewelers of Dresden, before moving to the United States in 1850.
After arriving in New York City, Herman worked as a designer at several prestigious luxury firms, including Ball, Black & Co., Tiffany & Co. and was a partner at Starr and Marcus before he went into business with William. Later, they were joined by Herman’s other son, George.
Herman worked with his sons until his death in 1899, when William and George expanded the firm to include a silversmithing department to make serveware. However, Marcus & Co. focused mainly on jewelry design and manufacturing, offering Revival-style pieces.
In 1900, the company exhibited a series of striking orchid motif brooches at the Exposition Universelle in Paris. The brooches attracted critical acclaim for their plique-à-jour enameling and intricate detail — characteristics that would become Marcus & Co.’s signature.
The company’s Art Nouveau jewelry took shape during the 1920s and 1930s. Cocktail rings, engagement rings, necklaces and cufflinks featured fine diamonds, natural pearls and gems rarely seen during that period, such as peridots, zircons, spinels and chrysoberyls. Marcus & Co.’s designs were comparable by critics to fine art jewelry made by René Lalique and attracted high-profile clientele like business tycoon John D. Rockefeller.
Despite Marcus & Co.’s success, the firm closed briefly during World War II. In 1962, they merged with the company Black, Starr & Frost.
Marcus & Co. pieces are still highly coveted among jewelry collectors. The firm’s Art Nouveau plique-à-jour accessories, a technique that sees enamel powder applied to cells on a thin sheet of copper foil or mica and then etched away — instead applying the enamel directly to metal — are particularly collectible. In 2011, a Morning Glory plique-à-jour pendant brooch and chain made in 1900 sold at a Sotheby’s auction for $302,500.
