Cartier Carat Perfume by Cartier 3.3 oz Eau De Parfum Spray (Tester) for Women. Cartier carat is a new 2018 fragrance by the renowned jewelry design house. This diamond-inspired scent strives to unite seven separate elements, just like the seven colors in a prism. These are represented by seven distinct floral notes: tulip, violet, honeysuckle, lily, narcissus, hyacinth and ylang ylang. This playful, feminine eau de parfum is the brainchild of cartier fragrance designer mathilde laurent. The light-catching, faceted bottle also reflects this scent’s prism theme. It’s an enchanting scent best worn in the spring.
