"Topping the sale in some style were the Cowdray Pearls, a necklace featuring 38 graduated natural grey pearls formerly owned by the Viscountess Cowdray, Lady Pearson (1860-1932). Estimated at ?280,000-350,000, the necklace rapidly surpassed this valuation on its way to a stunning new world record price for natural grey pearls of ?2.2m - 519% above its high estimate.
Each pearl set on the necklace has a unique colour as they are untreated rare natural saltwater pearls. The necklace is the perfect neck length at 43.2 cm long. The clasp of the pearl necklace is joined together with a striking rectangular mixed cut diamond measuring 11.4 -6.8mm."
