Boucheron Plume de Paon Ring 54As if captured in the material, this Plume de Paon ring in titanium and white gold, which is set with an oval tanzanite in its center, delicately wraps around the finger. A real innovation is the use of titanium, a metal 3 times lighter than gold, chosen here both for its lightness and to create these gradations. The colors of the strands, paved with sapphires, tsavorites and diamonds, gradually fade, like a real peacock feather. MATERIALS: White gold
