Sauvage Privé jewels Roberto Coin chose to leave the rules of classic fine jewelry behind when he created his Sauvage Privé collection. The design’s unrestrained, boldfaced geometry goes far beyond innovation. The same impulse is reflected in the unusual choice of stones used to decorate the collection. Black jade, which is extremely difficult to cut, is the shiny, forceful star of the collection. And the malachite, with its naturally unique design is the perfect advocate for the company’s mission: to dedicate an exclusive piece of jewelry to every woman.
