Rio Tinto showcases historic collection of rare coloured diamonds
Rio Tinto has launched its 2024 ‘Beyond Rare’ tender, the second in its Art Series offering, showcasing 48 lots of extraordinarily rare masterpieces of nature from its diamonds business.
Titled ‘Colour Awakened’, this collection is headlined by seven notable historic diamonds from Australia’s Argyle diamond mine that operated from 1983 to 2020.
These so-called old masters comprise seven round brilliant cut, pink and red diamonds, ranging in size from 0.60 ct to 2.63 ct. All unearthed from the mine over a decade ago – in one case, as far back as 1987 – each diamond has been carefully retrieved from private vaults and handpicked for inclusion in this year’s tender.
In London at the launch of the event earlier this week, Rio Tinto Minerals CEO Sinead Kaufman said: “No other mining company in the world has custody of such a kaleidoscope of coloured diamonds. Four years on from the closure of the Argyle mine, our Beyond Rare tender platform is a testimony to the enduring prestige of the Argyle pink diamonds brand, the quality of production from our Diavik mine, and the ongoing demand for highly collectible natural diamonds.”
In addition to the old masters, the Art Series 02 includes legacy inventory of pink, red and violet diamonds from the Argyle mine, together with white and yellow diamonds from Rio Tinto’s Diavik diamond mine in the Northwest Territories of Canada.
In total there are 76 diamonds, weighing 39.44 ct, comprising seven old masters, including one fancy red diamond, 32 single lots of pink and violet diamonds, including one fancy purplish red diamond; and a rarified offering of nine diamond sets, two sets including a 2.47 ct fancy intense yellow diamond and a 4.04 ct D colour diamond respectively, each from Rio Tinto’s Diavik mine.
The 48 lots will be showcased in London, Australia, Singapore and Belgium, with bids closing on November 18.
