On August 15th, the British auction house Bonhams will hold its “Pioneers of Pop Culture” sale. One of the big-ticket items on offer? A triple-strand fake-pearl necklace originally owned by none other than Jacqueline Kennedy Onassis. The champagne-colored “pearls,” which fasten with a faux diamond and emerald clasp, are expected to sell for upwards of $40,000, although a jewelry expert at Bonham’s acknowledged that the high price is due almost entirely to cachet conferred by the former First Lady. “The triple-strand necklace on its own would be worth at most in the very low hundred (pounds),” Jean Ghika said. “It’s fair to say that 99.9% of the value is because they belonged to Jackie Kennedy.”
