Rebel geometry



Mathematics made art.

Heptasik is the purest and most disruptive essence of Roosik. Where nature seeks the structural comfort of the hexagon, Jordi Rosich creates a new rule through the mathematical anomaly of the heptagon. The result is a collection defined by pure lines, architectural strength, and a subtle rock (or rebellious) edge.

High-engineering pieces crafted with such precise ergonomics that they defy classic rigidity, merging with your body like a second skin.

A bold and high-impact design, created to be worn with absolute freedom. Your everyday luxury, 24/7.

  • Natural Diamonds

    At Roosik & Co. we work with natural diamonds, because our commitment is not only to environmental sustainability, but also to social sustainability and dignification in countries like Botswana, which, no matter how far away they may be, are part of our same human community.

  • Jordi Rosich

    Jordi Rosich was born into a family of jewelers. Contact with materials and tools in the workshop was the natural habitat that nourished the passion he would later develop. After completing his secondary education, he undertook higher education studies in jewelry and gemology at the JORGC School of Jewelry and at the University of Barcelona.

  • WE CREATE. WE MAKE.

    At Roosik, we combine traditional techniques – such as hammer and anvil – with the latest technology – micro-casting machines and 3D printing. One of the main commitments we made as a brand from day one is to create all our jewelry pieces in a conscious and respectful way towards you and the environment, and all made in our Studio in Girona.
