In 1852, Leon Rouvenat revolutionizes jewellery. In 2022, Rouvenat revolutionizes eco-jewellery. Past, present, future: the cycle of creation. Rouvenat's creations are inspired by archives. Re-invented by Sandrine de Laage, they give the iconic "Bijou Rosace" of the time, a new breath full of meaning, symbols and hope. The pieces are made of recycled gold and silver, in continuity of the 19th century jewellery tradition. They highlight eco-creation: the jewel adapts to the gem, and not the other way around.
