In 1924, the visionary mind of Louis Cartier created the Trinity ring. Three bands intertwined in harmony, three colours of gold: pink for love, yellow for fidelity and white for friendship. The unique, timeless and cosmic Trinity design is now available as an 18K three gold diamond necklace. Trinity, all about you forever.
