But fittingly for a woman who once styled The Sex Pistols, these are not your mother's tasteful diamond studs. Instead, the collection, a sexy-sounding Vivienne Westwood Hardcore Diamonds, features riffs on some of the designer's favorite motifs: her signature royal-subverting orb symbol, oversize clocks, hearts and arrows, and, of course, safety pins, albeit white gold, bejeweled, and with price points starting around $600. Unfortunately for all but the most die-hard devotees, the piece that first previewed Westwood's latest obsession to the public—a diamond-covered devil horn tiara the designer wore to the opening of her 2004 retrospective at London's fabled Victoria & Albert Museum—is available by special order only.
