Twin sisters Roos and Geertje Eek

We are Tweek-Eek, an innovative jewelry label founded in 2019 by enthusiastic twin sisters Roos and Geertje Eek. Committed to sustainability, we exclusively manufacture our pieces in the Netherlands. We use massive machines that were not originally meant to produce jewelry, but are intended for furniture or high-tech industries. By repurposing these machines, we create unique shapes and patterns while also minimizing waste or ingeniously reusing it. This, in combination with our designs, makes our pieces innovative, rough, and yet elegant.
