As 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.
