American Modern – Marcus & Co jewelry
German born Herman Marcus came to New York in 1850 and began working as a designer in the famous company Tiffany & Co. However, after almost thirty years, he decided to leave the famous company in order to establish his own. Fortunately, his two adult sons supported their father and since 1884 the three of them have successfully worked at Marcus & Co. Fifteen years later, Herman died (1899), but his sons successfully continued to manage the jewelry company, already known both in New York and beyond.
Among the materials that they used to create the jewelry was multicolor enamel, precious and semiprecious stones. Traditionally, the jewelers of this company produced fine jewelry inspired by the culture of Egypt and the Renaissance, as well as the Art Nouveau style, popular in the early 20th century.
Noteworthy, Marcus & Co. jewelers studied the skill of enameling in the Paris workshop of the famous designer Rene Lalique. As a result, jewelry of this brand is rare, located in museums and are of collectible value.
Sold to Gimbels in 1941, the company merged with Black, Starr & Frost in 1962.
