Chairman's Notes

Oscar Heyman Brothers are known as the "jeweller's jeweller". The firm was founded in New York in 1912 by two brothers, Oscar and Nathan, immigrants who trained in Fabergé workshops in the years before World War I.

Their technical skills learned in the Russian workshop uniquely placed them to successfully attract the most prestigious firms as their clients, creating pieces for many esteemed jewellery houses including Van Cleef & Arpels, Tiffany & Co. and Cartier to name a few. They have created some iconic pieces including Taylor-Burton diamond drop necklace for Cartier in 1969.

Oscar Heyman creates jewelry that is as timeless as the very gemstones it holds. The highest degree of craftsmanship is applied to each process that brings a piece to life.
