The Duchess of Windsor is definitely another big contributor to the Cartier jaguar. In 1948 and 1949, the Duchess of Windsor owned two Cartier three-dimensional jaguar brooches, one of which features a jaguar paved with sapphires, white and yellow diamonds, resting on a 152.35-carat cabochon sapphire. Still the iconic work of Cartier. Since the Duchess of Windsor wore jaguar jewelry, Cartier’s jaguar creations have since become world-famous.
