Rio Tinto's Argyle Pink Diamonds has auctioned the first Argyle Pink Diamond Limited Edition O Pendant in a series of 100 numbered pieces.

The exclusive pendant was offered for auction by luxury Australian retailer Mondial Neuman and sold for A$14,500 (US$15,300).



Proceeds from the sale have been donated to the Gawura school, an indigenous school within St Andrew’s Cathedral School in Sydney’s inner city.



This donation of $14,500 will cover the costs for two children’s tuition fees for one year at the Gawura school. Gawura is an initiative that supports literacy and numeracy programs for Aboriginal and Torres Strait Islander children.



According to Josephine Archer, Business Manager of Argyle Pink Diamonds, "The 100 Limited Edition O pendants were much coveted as a commemorative piece of jewelry and this strong result is indicative of the increasing awareness of the value of Argyle pink diamonds."
