An ever-popular contemporary design, this iconic Cartier "Trinity" ring of interlocking white, rose, and yellow gold bands was designed by the artist Jean Cocteau. Best known as the leader of French avant-garde cinema, Cocteau excelled in many arts and, in 1923, gave this jewelry design to his friend Louis Cartier to create in gold. Deceptively simple, the smoothy rolling, three-part minimalist form is a little masterpiece of art and engineering for the hand, with the three separate bands of gold intimately intertwined.
