Our Story

Driven by the pursuit and passion of perfection, a fine attention to detail and an appreciation for true beauty, the brand Uniglo has made an indelible mark in the world of natural diamonds. It all started in 1988, as a family business which went on to become a unified brand called Uniglo, established in 2000 in Antwerp, Belgium, the city of diamonds.

Our Journey

For over three decades Uniglo Diamonds has represented the rarest and most beautiful natural diamonds in the world. With quality, service and perfection as the three-pronged cornerstone of the company, generations of the Uniglo family have employed their vast experience and expertise to create masterpieces that appeal to one and all—from the doting fiancée to the calculated investor. Painstakingly involved in picking the finest stones, with access to all the best, direct sources of rough natural diamonds, Uniglo promises perfection every step of the way. The brand’s in-house manufacturing unit is in India, and it ships all over the world, spreading the Uniglo name far and wide, gaining a reputation for its outstanding selection of diamonds and unparalleled excellence in service. The brand’s story of metamorphosis is in many ways very similar to that of a diamond – transforming from a raw, rough carbon into a precious, brilliant and refined gem. And the journey continues.
