During a walk in the Black Forest in the 1970s, Ronald Kurowski, a designer working for Chopard, was thrilled by the sight of a waterfall and the thousands of drops of waters escaping from it, reflecting the daylight and sparkling with all the colors of the rainbow.This vision sparked a brilliant idea: for diamonds to shine their brightest, they had to be freed from the claws that held them and allowed to spin freely.It was thus that the Happy Diamonds concept was born.“Diamonds are happiest when they are free". "It was in these words that Karin Scheufele, head of Chopard, welcomed the first creation with mobile diamonds. This expression caught on and the watch was named “Happy Diamonds”.
