Black, Starr & Frost - Wikipedia Black, Starr & Frost This company is the oldest continuously operating jewelry firm in the United States and the origins date back to the company of Marquand & Co., founded in 1810 in New York City by the silversmith Isaac Marquand, whose family immigrated from France. In 1839 the company was purchased by Henry Ball, Erasmus Tompkins, and William Black, and renamed Ball, Tompkins & Black until 1851 when it became Ball, Black & Company. In 1876 it acquired its current name, Black, Starr & Frost, when new partners Cortlandt Starr and Aaron Frost joined the firm. In 1860, the firm opened a store at the intersection of the corner of Broadway and Prince Street in New York City, and in 1912 they moved to the southeast corner of Fifth Avenue and 48th Street, known as the diamond district. In 1929 it merged with Gorham to become Black, Starr & Frost and Gorham. During the interlude from 1940-1962 it was known as Black Starr Frost Gorham as it partnered with Gorham Manufacturing Company; however, the name reverted to Black, Starr & Frost in 1960. Indeed, the most influential families of the time were its clients. Among them, in particular, Carnegie, Vanderbilt, Rockefellers, Guggenheim and Windsor. The company opened one of the first stores on Fifth Avenue in New York. It was here that celebrities and royal families bought some of the largest gems in the world. By the way, Marilyn Monroe mentioned the company in one of her popular songs, “Diamonds Are A Girl’s Best Friend.” Millegrain This is a jewelry technique which refers to the textural effect of a close-set line of metal beads that are typically used as a border on the edges or bezels of jewelry.
