All eyes landed on the pearl station necklace, better known as the Tin Cup necklace. The style was a smash after actress Rene Russo, to the dismay of her directors, wore designer Wendy Brigode's spaced-pearl necklace in back-to-back starring roles in fall 1996 – in the movie that became the style's namesake and two months later in Ransom.
The original design by Brigode used 7mm to 8mm baroque Japanese cultured pearls strung with even spaces between. Takeoffs abounded at the trade shows that winter: versions used freshwater cultured pearls, dyed pearls, gold and silver chains, even Tahitian black pearls spaced to save on cost.
Many jewelers also don't know that "Tin Cup necklace," the term used frequently on signs and in conversation, is a protected name, though Brigode is not legally defending it. "Warner Bros. gave me permission to use 'Tin Cup' as a trademark of that movie, so theoretically no one else can use it," she says. The politically correct and legally precise alternative: "cultured pearl station necklace."
