Rene T. Doumeng is a fifth generation master jeweler.  Interesting fact, Leon R. Doumeng, Rene’s great grandfather, was employed by Cartier.  He was considered to be one of their top jewelry designers. Leon split his time between Cartier’s New York and Paris stores.

In the 1930’s, Rene’s grandfather, Paul Doumeng, owned and operated the largest diamond setting trade shop in New York located at 133 Canal Street, New York, NY. In 1948, Paul, along with his son Rene, (Rene’s father), relocated and opened the family’s first retail jewelry store in Hempstead, New York.

Rene started to work full time in the jewelry business right out of high school in the Hempstead store.  Here he apprenticed under the guidance of his grandfather and father. Eventually that store was relocated to Massapequa, New York.


In his early thirties, Rene Doumeng embarked on his own opportunity and successfully opened Rene Doumeng Fine Jewelry in East Islip, New York.  In March of 2017, after over 30 years in East Islip, New York, Rene has relocated his talents and business to the North Fork of Long Island where he works today in his studio by appointment only. He also maintains an office in New York City.
