Last week, I had the opportunity to visit the Cartier Mansion on Fifth Avenue in New York and tour their private rooms, an experience I won’t soon forget. Originally built in 1905, the landmark building is one of New York’s last remaining gilded-age mansions. It was once home to Morton Plant, who traded the building in 1917 to Pierre Cartier for a rare double-strand natural pearl necklace that caught the eye of his wife Maisie, worth 1 million dollars at the time.

Today, the building is home to Cartier’s American flagship store known around the world for it’s glamorous oak-paneled salons which blend the grandeur of the gilded-age with modern sophistication. Many of the rooms are named after the Maison’s most renowned clients, like Princess Grace of Monaco, Elizabeth Taylor, and Gary Cooper, where archival illustrations hang alongside relics of the past such as drawings by Jean Cocteau, a polaroid self-portrait by Andy Warhol, and the royal warrant of Britain's Queen Alexandra. These rooms, which reflect the Maison’s rich heritage, showcase Cartier’s finest watches, home objects and haute joaillerie.

One of the mansion's modern features is the interactive scent room, a multi-sensory experience created by Cartier's official perfumer, Mathilde Laurent, which allows clients to immerse themselves in house fragrances. The adjacent room which houses fine leather goods, home decor and one-of-a-kind horlogerie is designed to make you feel as if you've stepped inside one of Cartier's signature red boxes.

Next, the highlight of our visit, we were lead through a secret door to the private salon of Jeanne Toussaint, the "panthere" herself. The salon, exquisitely decorated with Louis XV furniture and herringbone wood floors, pays homage to Louis Cartier's legendary muse who went on to become Artistic Director of Jewelry, creating some of Cartier’s most iconic pieces, including the Duchess of Windsor’s flamingo brooch and Barbara Hutton's bejeweled cats. It was surreal to see her original sketches with her handwritten notes up close.

Before heading out, we returned to the Panthere salon for a glass of champagne, the perfect way to top off our visit.
