Carat, the new fragrance from Cartier, bottles the seven colors of a prism that converge into a single pure scent, akin to a diamond. Capturing the light, the diamond bottle inspired by Art Deco diffracts the colors of a prism and mirrors their reflections in its glass square-cut facets. "I wanted to create a fragrance that shimmers with all the fire of a diamond. It occurred to me to apply the principle of diffraction to the fragrance: Dispersed light appears as flashes of rainbow colors in a diamond. And so, I chose seven beautiful fresh flowers that come together to form a new flower, abstract but alive, like the light of the diamond." - Mathilde Laurent, Cartier perfumer
