Founded by John Nanasi in 1964, Nanasi Enterprises started solely as a loose diamond supplier. At the time, Nanasi Enterprises was centrally located in the New York City Diamond District, and John and his family established strong connections across the diamond supply chain. As the diamond industry evolves, Nanasi Enterprises refines the process through which we source diamonds. Today, with over half a century of experience, we are more rigorous than ever about ensuring the origins of our diamonds meet our quality and ethical standards.
Nanasi Enterprises rapidly grew, and so did the demand of our customers. We started to manufacture diamond jewelry, and then solid gold jewelry. Through a series of partnerships, we formed departments that specialize in different jewelry crafts. Each department sources the best materials and craftsmen for their needs to ensure the best value for their products. Together our group of companies, NEI Group, is able to provide jewelry buyers with products that meet most of their needs.

NEI Group works with retailers across the US, Canada, and the Caribbean and we've designed and created private label collections for retailers including Bloomingdale's, Fortunoff, and Bailey Bank's & Biddle. We outgrew our space in New York City and with deep, widespread connections in the industry we no longer needed to be located directly in the diamond district. In 1985 the NEI Factory moved to New Jersey.
NEI Group is still a family business; and our family has grown to include many new members. Our team includes people from more than 6 countries with over 500 years of combined experience in the jewelry industry. We are proud to be a diverse team of experts.
