Roulette or Happy Diamonds
Boodles · Chopard
Roulette
A small ring of brilliant-cut diamonds that turns over as the wearer moves, showing diamonds on one face and plain gold, or more diamonds, on the other.
Happy Diamonds
Diamonds set free between two sapphire crystals, so they slide and tumble with every movement of the wearer.
Chopard frees its diamonds; Boodles turns them over. Happy Diamonds, born on a 1976 watch by Ronald Kurowski, encloses loose stones under sapphire crystal so they scatter and gather as the wearer moves, a waterfall caught in a round case. Roulette keeps its brilliants set but makes the whole circle swivel, diamonds on one face and polished gold, or more diamonds, on the other. Both move, but Chopard's motion belongs to the stones and Boodles' to the setting.
