一些我查到的资料： It was created for Cartier by Jean Cocteau (the artist). All sorts of other jewellers have this ring and called it various names, like 'the rolling ring' or 'russian wedding ring' (3 bands together, it is russian tradition) The Trinity collection originally relseased in 1924 by Cartier, has since come quite the long way and become one of the most incredible rings known today. This ring is a representation of the various stages of a relationship intertwined. These stages are shown through three different colors of 18-karat gold. White gold for friendship, rose for love, and yellow for fidelity. The latest and greatest version of this ring incorporate style & taste friendly diamonds making this work of ‘fingure-art’ quite noticeable.
