Of all diamond colours, pink is the most intriguing. Unlike other coloured diamonds, the phenomena of pink diamonds remains in part a mystery. It is thought that the pink colour is created by a twist within the atomic lattice during formation, the result of immense heat and pressure beneath the earth’s surface—a fabulous fluke of nature.
The finest and rarest diamonds are reserved for the annual Argyle Pink Diamonds Tender, which is widely referred to as the most exclusive diamond sale in the world. The event highlights a small number of important diamonds from the Argyle mine that stand apart from their peers in terms of vibrancy and intensity of colour. The 50 to 60 of the most extraordinarily rare pink, red and violet diamonds that are offered as part of the Tender represent less than 0.1 percent of diamonds ever unearthed from the Argyle Diamond Mine.
