Oscar Heyman & Bros is an American jewelry firm and manufacturer that first gained attention in the 1920’s. In 1906, Oscar and Nathan Heyman immigrated to the united states from Latvia. Thanks to an apprenticeship at their great-uncle’s Faberge workshop, they arrived with a skill that made them instantly employable: They could work with platinum, a metal relatively new at the time. Oscar was hired to work in Cartier’s first New York workshop at 712 Fifth Avenue, he was the first non-French bench jeweler hired by the firm. When the whole family moved to New York in 1912, Oscar, Nathan, and Harry Heyman founded the company in the same year. They were later joined by their three younger brothers, George, William, and Louis, along with two sisters, Frances and Lena. In 1970, Oscar Heyman died, and his youngest brother, George, took over the business. The company continued to expand globally during the 1970s while still making products for other high-end jewelry businesses and selling directly to department stores such as Neiman Marcus. Other Heyman family members have continued to run the company over time, with the current president being George's son Adam Heyman. The company's jewelry is still highly regarded and frequently worn by celebrities on the red carpet.
