Roulette or Happy Hearts

Roulette shows two faces by turning over: a little wheel of diamonds that swivels to reveal diamonds or polished gold on the reverse. Happy Hearts shows two at once. Since 2009 Chopard has set a solid heart of mother-of-pearl, onyx or a red stone beside an open one in which a single diamond rolls. The heart is a sentimental sign with a wandering stone inside. Boodles sells its wheel as an alternative to the eternity ring, so it carries a sentiment too, only without a symbol.
