About Zen Diamond
The roots of Zen Diamond date back to 1906, when the founding family began its passion for jewelry craftsmanship. In 1998, the company was established by Emil Guzelis, the youngest son of the family.
Between 1998 and 2005, Zen Diamond opened wholesale branches in New York, Antwerp, and Dubai—three locations that continue to operate today, generating around 40% of the company’s annual revenue. Our strong presence in the wholesale market enables us to offer a diverse product range at competitive prices to our retail customers as well.
With 67 stores worldwide and a central office employing 270 people, Zen Diamond stands for expertise and quality. Additionally, 480 skilled professionals work meticulously in Europe's largest diamond jewelry production facility.
