Torrice, Italy

The idea of the secret meaning is at the core of all I make. Since my philosophy studies, my work has always been about mystery and discovery. In the efforts of building a straight line between my inner world and designs, I tripped over a question: were the materials we were using as fair and authentic as the meaning they would have preserved? Beautiful esthetic should come along beautiful ethic. We began questioning our suppliers and learning more about the dynamics behind gold, pearls and gems. Since then, we introduced Fairtrade Gold in Italy and continue to look for the fairest precious materials.
