The American firm of Hammerman Brothers was founded in New York in 1946 by Benjamin, Hyman and Bernard Hammerman. The three brothers had all recently returned from war when they decided to go into business together and set up a jewellery manufacturing company. They built their reputation on making high quality fine jewellery in 18ct gold and platinum set with beautiful gems. in the 1960’s The Hammermans manufactured gold bracelets for the Bulova Accutron, the world’s first fully electronic watch.Over time they expanded their business vertically with the introduction of the Kelman Casting Company and the Bermont Diamond Company meaning that as much of the process and supply could be brought in house as possible.
