Renowned as "the costliest perfume in the world," the Joy line was created in 1930 by haute couture designer Jean Patou. One ounce of the lavish scent contains 10,600 jasmine flowers and 28 dozen May roses. The luxurious composition is coveted by women around the world. The bottle of Joy follows the principles of divine proportion, a mathematical device used by the Ancient Greeks to achieve perfect proportions in architecture.
