About Us

Julius Cohen was founded in 1956 as a fine jewelry design house dedicated to the highest standards of quality, craftsmanship and service. Recognized throughout his career as one of America’s premier designers of fine heirloom jewelry, Julius’ passionate dedication to beauty, quality, and integrity formed the basis of the company’s reputation.  But, it was his sense of fun, charm and the celebration of life that came to define both the creative process and our customer relationships.  It’s a legacy that’s lasted three generations and that we continue today.

For over sixty years, we’ve been making beautiful fine jewelry, marking special occasions and celebrating the everyday.  Every piece we make, whether a collection piece or a custom project, is given the same attention to detail and commitment to the highest quality of stones, metal and craftsmanship.

Please contact us for interest in our collection or for assistance with the creation of your unique piece of jewelry.  We’re happy to hear from you!



Julius Cohen began his jewelry career in 1929, at age 16, working for the prestigious company of Oscar Heyman & Bros, owned by his uncles. There he learned the rudiments of the trade and the craftsman skills of the European apprenticeship system. He also began traveling extensively in the United States, meeting new customers and understanding the emotional involvement a jeweler can have both with his creations and with the families that acquire those creations. Later, he joined the firm of Harry Winston in New York, another very illustrious jeweler, where he was responsible for developing new markets, particularly in Texas. In 1956, with his extensive training and expertise, he established his own business of designing and manufacturing fine jewelry for a select audience of customers around the United States. His new firm, bearing his own name, focused from its very beginning on producing well-designed and well-executed jewels with fine metals and precious stones. The excellence of his work made him eligible for induction into the pantheon of celebrated jewelry designers, winning the coveted Diamonds-International Jewelry Design Award for several years consecutively. Julius Cohen passed away in 1995, but his work and spirit of constant creativity continued through his daughter and son-in-law, Marjory and Leslie Steinweiss, who continued the business of Julius Cohen New York.

Leslie Steinweiss joined the company in 1975 and soon became its creative driving force. In fact, for 30 years he directed the development of new designs, including many which have become classic signature pieces of the company. At Julius Cohen New York, Leslie and Marjory continue the standards of excellence that were originally set by Julius, creating new pieces while delivering the highest level of service that has earned the company generations of devoted customers.  

Their daughter Parsley, Julius’ granddaughter, started with the family business in 2005, and has served as Creative Director since 2012.  She brings her skills and training in fine arts to a new generation of Julius Cohen design.
