Titled Into the Light, this unique event marks a special chapter in world diamond history. With Rio Tinto’s Australian Argyle Diamond Mine ceasing operations in November 2020, and the Diavik Diamond Mine in Canada ceasing production in 2026, the final collection of the Art Series pays homage to the life of these iconic mines.
The collection, weighing 45.44 carats, is headlined by six ‘Masterpieces’ - diamond sets carefully selected to showcase the pinnacle of production from these two famed mines - together with 39 single diamonds and an additional seven curated sets of diamonds.
Patrick Coppens, General Manager of Sales and Marketing for Rio Tinto’s Diamonds business, said: “It is hard to overstate the importance of this final collection from two extraordinarily beautiful places on earth - the East Kimberley region of Western Australia and the Northwest Territories of Canada.
“No other mining company in the world has custody of such an exquisite collection of diamond colours, shapes and sizes and we all pay tribute to the men and women who have worked so hard over many years to bring them to market.”
The Argyle pink, red and violet diamonds have been curated from the final legacy inventory, representing some of the last of their kind in the world:
- One GIA Fancy Red diamond;
- 12 GIA Fancy Violet diamonds; and
- 76 GIA Fancy Pink, Purple-Pink and Purplish Pink diamonds.
The collection showcases the quality of production from the Diavik mine with two D-colour white diamonds of Flawless clarity, including a 5.11 carat Emerald cut and a 3.02 carat Pear shape, each diamond meticulously crafted from the same original rough diamond. The collection also includes a Fancy Vivid Yellow diamond weighing 6.12 carats.
The diamonds in the final Art Series, revered for their pure and clean provenance and the kaleidoscope of colours, are expected to be in strong demand by the world’s finest jewellers, collectors and diamond connoisseurs.
The 52 lots will be showcased in Hong Kong, Australia and Antwerp, with bids closing on 20 October, 2025.
