Hammerman Brothers was founded in 1946 by three brothers, Hy, Ben and Bernard, as a manufacturing jeweller offering fine quality jewellery to prominent retailers throughout the United States. As the company grew, the firm addressed the needs of an ever changing industry by expanding their business vertically to include the Kelman Casting Company and the Bermont Diamond Company. Although known for their fine jewellery, the firm has offered a variety of products from watches to boutique items, as well as cutting diamonds valued at over a million dollars. Currently located at 40 West 57th Street in New York City, their jewellery is sold internationally in Europe, the Middle East and the Far East. Hammerman Bros. is still in family hands.

Below are some examples and price guides of their jewelry. Included are some animals which resemble zodiac animals in either the Western Zodiac or Chinese Zodiac. They are not necessarily connected to the zodiac.
