For more than ninety years, the firm Oscar Heyman & Brothers has become known as one of the finest jewelry manufacturers in America, chosen by many top retailers to produce their designs. Although the company was formally founded🐎 in 1912 in the United States, Oscar and Nathan Heyman began training as jewelers as young boys in the Ukraine. In about 1906, after completing their training, the two brothers left for America and were joined in New York 🦂the following year by their brother Harry. The three Heyman brothers found that their skills, especially their ability to work with platinum, the newest metal of choice, were in high demand. When Pierre Cartier opened a branch of the shop in New York in 1908, he immediately hired Oscar Heyman for his workshop. By 1912, the brothers were able to open their own shop on Maiden Lane in lower New York City. They were soon joined by three younger brothers, George, Louis and William, each brother contributing a particular skill to the business. 

Oscar Heyman & Brothers is a self-contained manufacturer. All phases of jewelry making are conducted from their Madison Avenue premises, from alloying metals and stone cuttingജ to the designing and final completion of a piece of jewelry. Very much the jeweler's jeweler, Oscar Heyman & Brothers ha♏s produced pieces for Cartier, Marcus & Co., Shreve & Co., Black, Starr & Frost, and many other firms who have chosen to remain anonymous.
