Must De Cartier Gold by Cartier Perfume. Created by the House of Cartier and perfumer Mathilda Laurent, Must de Cartier Gold is a new twist on the original Must fragrance. Released in 2015, this floral perfume mixes earth with elegance for a rich fragrant experience that captivates and transitions well from day to evening. The warm base note of creamy vanilla underlies the middle chords of jasmine and osmanthus. Topped with galbanum and green leaves, this fresh perfume brings a sweet lightness to your everyday essence.
