Coloured Diamonds: Why They’re Rare, Valuable and Incredibly Collectible

In the world of diamonds, white may be the standard, but colour is where the magic really happens. From blush pinks and oceanic blues to canary yellows and rare violets, coloured diamonds are nature's most extravagant anomaly. 

Formed over millennia by trace elements and atomic quirks that lend them their unmistakable hues, their allure is nothing new. 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.
