DIAMOND LIFE: Crisis, what crisis? On Wednesday, Cartier International’s chief executive Bernard Fornas described robust demand for special orders — high jewelry pieces designed by Cartier for elite clients. “It’s the ultimate luxury,” he said. Fielding questions after screening the brand’s new 3.5-minute commercial, “The Cartier Odyssey,” he said its workshops now turn out more than 100 special orders for clients around the world. He declined to assign a value, but said explosive growth in global wealth underpins the trend. Clients are allowed input on special orders, but all elements must meet the jeweler’s creative and quality standards, Fornas said. Cartier’s creative department numbers about 30 people, spanning 11 nationalities.
