This unique piece from Cartier performs its magic on a multitude of levels, from the lavish gemsetting and design of the pendant to the mystery tourbillon movement gracing the dial. A combination of diamonds, sapphires and onyx - designed to evoke the outstretched wings of a butterfly - form the body of the white gold pendant with its detachable 25.93-carat oval Ceylan sapphire dangling graciously below. Once you’ve got past the dazzling beauty of this piece you will notice a whirling double tourbillon suspended in the void at the top of the pendant. Known as a mystery tourbillon, the complex mechanics allowing it to twirl are hidden from the viewer enhancing the spellbinding effect of this timepiece. The price of this pendant watch is €1,500,000.
