Diamanjóia was founded, in 1989, in Portugal, by Dulce Maria Rocha. Since the beginning the company distinguishes itself by a contemporary design, the use of rare materials and the influence of the trends occurring in Europe.

In 2000 the company reinforces its position as a market leader with the opening of a new House and Workshop, where tailor-made solutions are proposed to selective clients. Inspiration and technical capability together result into true marvels of the handmade creation.

In a Society undergoing constant changes, Diamanjóia became in 2002, the first company in Portugal to own its original brand – GATTO.

From the surprising shapes, polished to perfection, overcoming the impossible, GATTO collections merge the talent and the expertise of the craftsmen opening way to sophistication.
