Georgina Chapman Moves Outside the Marchesa Realm October 20, 2008 5:32 pm >> Now that Georgina Chapman has officially realigned herself as the designer of Marchesa, leaving Keren Craig, former co-designer, to the more business side of things, she's branching out beyond Marchesa.Garrard, the British jewelry brand that supplied Princess Diana's engagement ring, is seeking a creative director since Jade Jagger left the post in 2007, and in the meantime, they've asked Georgina to be a guest designer. The Georgina Chapman for Garrard collection is to be unveiled next September during New York Fashion Week — no doubt accessorizing the Spring 2010 Marchesa collection — and prices are expected to run in the $10,000 to $15,000 range.
