The French jeweler and watch company Cartier, founded in Paris in 1847, gained international fame in 1904 with the 'Santos de Cartier', a wristwatch created for the famous Brazilian aviator Alberto Santos Dumont. With their Paris boutique established in the Rue de la Paix, Cartier soon opened further branches in London, New York and St. Petersburg to cater to the demand of a growing international clientele. Cultivating ties to important members of the aristocracy, Cartier became the supplier to the most notable royal dynasties of the 20th century. The famous Panthere motif, for example, was introduced with a ring specially made for the Duchess of Windsor. Since the beginning, Maison Cartier created innovative pieces of jewelry, inspired either by flora and fauna, or simply by the natural beauty of untreated stones such as Indian sapphires, Burmese rubies or Colombian emeralds, often amplified by innovative designs and extravagant combinations with other, smaller stones.
