Oscar Heyman Bros.: The Heyman family, consisting of nine siblings, emigrated from Russia to New York in 1906. Two of the brothers, Oscar and Nathan, had apprenticed at a Faberge factory, while another brother was an accomplished toolmaker. Together, they launched Oscar Heyman & Brothers in 1912. The brothers were master platinumsmiths who utilized only the finest diamonds and colored gems. In time, the firm manufactured and supplied jewelry for the most prestigious American jewelry houses of the 1930s. Flower brooches became the company’s signature item. Their magnificent creations are often unstamped, and require specialist authentication. Oscar Heyman & Brothers continues to be a self-contained, family owned and operated business where the old world techniques of tool making, fine platinum and gold metalsmithing are employed in the production of each piece.
