History's most captivating diamonds have often been coloured: the 59.60-carat Pink Star diamond, which shattered auction records at Sotheby's in 2017 when it sold for over $70 million; the Oppenheimer Blue, a 14.62-carat vivid blue stone once worn by royalty; and the mysterious Dresden Green Diamond, housed in a museum and cloaked in centuries of legend.
